Actually, lift does come into play with the Wikipedia explanation, but they just don't spell it out. The upwind wing has a higher AOA... It's a well established fact that increasing AOA increases lift. I was essentially explaining the same thing as the Wikipedia article, but in a slightly different wording.

When I mentioned lift, I didn't mention exposed surface area because, as the article states, it's an illusion. It does come into play when considering the yaw and ensuing sideslip.

Boy, FatOrangeKat you really got more than you bargained for didn't 'ya?

The Wikipedia definition explains clearly where the lift that reestablishes the horizontal orientation comes from. Increased AOA from the yaw.

The lift vector in their definition also comes into play in their description of the common misconception.

I'd say they spell all of it out. As your post did as well. What's wrong with adding documentation to already expressed arguments? Supporting evidence builds a case, doesn't it?
