In other words, if I have overlapping custom or lookalike audiences in the SAME ad set, overlapping shouldn't matter, right?
That's right. In fact, nowadays the targeting algorithm is pretty smart compared to the early days of FB ads, and does a pretty decent job of sorting things out on its own.
Unless my cost is unusually high, I wouldn't try to sort out any overlapping on my own or I may upset Facebook's optimization.
