"Even in cases where someone bi-amps in a single system, there are two amps driving the speaker which in many/most cases is connected internally via crossover - regardless of how many binding posts are on the speaker."
I don't think anything's "connected internally via crossover" for a system designed for bi-amping: such designs use parallel crossovers (aka electrical filters): each driver has its own filter. It would only be a problem for series crossovers, but they are much, much, much less seldom used and no designer would put another set of binding posts on such a system. I believe.
