A year ago, with my D4, all my pro lenses, four speedlights, plenty of backup equipment, and being published as a photographer dating back a lot more than 10-15 years, and several years experience running my wedding video biz doing high-end weddings, I could not get a CL job as a 2nd shooter. Why? Cuz I hadn't shot 10 or 15 or 25 weddings, so they hired someone like the photographer you mentioned instead. The world of wedding photography is a pretty crazy place to be.
Now that a year has passed in which I shot a grand total of 13 weddings, I still don't qualify to be a 2nd shooter for a lot of these photo companies that like to hire 2nd shooters off of CL. But that's okay, as my wedding packages sell at a pretty good number and I'm doing fairly good at booking up 2013.
But bottom line, some photo studios just want someone who can shoot the shots and don't really care that it's all on Auto mode and TTL direct flash. You get what you pay for.
I do beg to differ with your comment about wedding photography not being artistic. Sure, a lot of it is purely documentary work, but there's still your own personal style that you can stamp on these shots. Beyond that, you get to do some gorgeous shots in the golden hour, and you get to get all creative with some night shooting. You learn quickly how to get some gorgeous mid-day outdoor portraits. And... you sink or swim.
