The link at 11 doesn't know about the rest of the chain. It is pulled by the link in front of it, and while that isn't tangent, it isn't at all the chain links going toward the chainring at the top.
Yes, that's basically what I said, and I'm not sure if you misunderstood or not. The wear happens between 11 and 12 o'clock or so as the line of pull swings from a secant to the tangent. With a new chain and sprocket the wear ends there as the tooth drops clear. But with a worn chain, the wear continues as the tooth passes 12:00 and the roller rolls up the back while disengaging. Either way, wear happens during the moment of disengagement under load, with the wear rate increasing with sloppy (worn) fit.
