The point of EC in M mode, at least for me, is that Sony doesn't let you select a minimum shutter speed for auto-iso. It just defaults to something close to the 1/focal length rule.
In other words, a 28mm lens may use 1`/30th, a 50mm lens 1/60th and so on. The camera will only increase the ISO far enough to keep that minimum speed. Thing is, 1/30th, for example may not be fast enough to freeze subject motion, or if your shakey like me, 1/60th at 50mm may still produce camera shake. I usually like about 1/125th, and the higher ISO's are so good these days, I'd rather shoot at a slightly higher ISO than risk some camera shake at a lower ISO.
A lot of camera's will let you select a min. shutter speed. So you can tell the camera to always increase the ISO to keep, let's say, a 1/125th shutter. Only little catch with this is it isn't focal length specific so what you might want for a wide angle could be different than a longer tele. You have to select just one, or go into the menu to change it when you change lens.
What Sony does though is let you use auto ISO when in M mode, so you can select your aperture and ALSO your shutter speed, which in effect serves as your min. shutter speed.
If you want 1/125th, that is what you set it to. If your subject is moving faster and you want 1/250th, that is what you set it to, so on and so forth. Camera just automatically adjust ISO to let you keep that setting.
It actually works better than most auto-iso with min. shutter settings because it is on the fly. So that is great. A lot of other cameras don't have auto-iso in M mode even, so your stuck at a fixed ISO and have to keep changing it or your SS/Av value to compensate.
Where this becomes even better is that Sony gives you EC even in M mode with auto-iso. Most cameras don't let you use EC with M mode, because, well its manual mode lol. Even if they have auto-iso, your stuck with default metering and no EC. If you want to underexpose with a given setting, you need to manually set the ISO to do so.
The beauty of having EC though is that it turns M mode, with auto-iso, basically into a combination SS/Av mode.
Its like shooting in Av mode, where you'd normally use the EC on the fly to adjust for backlit subjects etc, and its also like SS mode where your telling the camera the shutter speed you want it to always use.
Its giving me the ability to shoot at the aperture I want the camera to stick at, and also the shutter speed, PLUS let me keep those same settings even if I want to over/under expose the shot, because its adjusting ISO.
I think its the best way to shoot, because there is so little issue with using a higher ISO when needed these days.
If I want to always be shooting at f4, 1/160th when out on the street, camera will always give me that and just bump up the ISO should I be in the shade or shadows, and should I see a subject that needs maybe plus 1 EC, I just turn the dial (assuming the EC dial is active  ) just like I was in Av mode.
Again, the benefit is that unlike if I was in Av mode and wanted to change the EC, the SS won't change. If I'm at 1/125th and F4 and I wanted to overexpose a stop, I don't want the camera dropping my shutter to 1/60th.
Hope that makes sense, its kind of a tough concept to explain
Best advise would be just try it on your camera. Turn out auto-iso, go into M mode, and play around with it

Thanks for the interesting info about Auto-ISO in M-mode and EC.
I now tested it and found that EC can be activated by down-click and then turning the rear wheel. Rear wheel by default is exposure, top wheel is aperture.
I can understand that its not nice that the Sony decides to assign aperture to the top wheel even if you assigned ec to it in the other modes. But then, I personally see this as a minor thing and probably more helpful for most than sticking with EC on the top, because in M-Mode you usually want to have S/A directly accessible. Unless your using a manual lens of course :-).

(Seriously, the Sigma 30 is a outstanding lens...even more so given the price, but the Sigma 60 is even better. )
