I'm probably making a mistake dipping my toe in this, but what Rusty is saying is that when you have natural lighting like this, there is actually nothing that the photographer is adding or subtracting from the light. You're just using the ambient light that is there, just like someone taking an iphone photo. Now, naturally, you saw the very good ambient light and you utilized it well.
I think the point you're missing is that Rusty is simply saying he was surprised that you did a shot like this where you did not manipulate the light, as he considers you masterful at that. I know you're not taking it that way, but he's actually trying to give you a very nice compliment, and somehow it's rubbed you wrong. I re-read his OP and I'm not really sure where he's rubbed you wrong, but rubbed you wrong he has. And it's kind of a shame.
As for my comment above, it had nothing to do with your picture or post, but someone asking why a professional would post in here, whether it's for the fanboys to give them love, or if he'd actually like meaningful helpful feedback. And as a professional photographer, I thought I'd answer this question.
I was not meaning to say anything about how you responded to Rusty or anyone else. When I see someone respond like that, I just steer clear of their posts. But I will say Rusty has been on FM a long, long time, spends a lot of his time on the Critique forum, and he's got a heart of gold and is really here to try to be helpful and encouraging.
I hope in some small way this helps.

The point was about the uber-soft lighting, and that when uber-soft lighting is present, it essentially offers the same look whether it is shot by a skilled craftsmen, or a rookie. Again, this is completely false.
