I'm not sure what your question is, but I can say this. I do have bikes with some overlap and I used to worry about it. Then I read a similar statement here in BF and it tweaked my interest. So fairly recently I've watched my wheel when I turned just to see how it worked. It is true, unless you (or at least I) are turning very tight such as in a u-turn the wheel never turns enough to enter the arc of the toe clip. And that explains why I've never experienced any trouble despite my bikes' setups.
