AFAIK, there is no added compensation for reverse. It's just a bunch of FETs hooked to the + rail and - rails, and the brains tells which FETs to turn on at any given time. Direction is determined by the order in which they are turned on.

Also, there are no "reverse" FETs. Each phase has FETs that lead to the + rail, and an equal number leading to the - rail (ground). Since there are 3 phases and 2 banks of FETs per phase, the total FET count is a multiple of 6.

Look up "H bridge" online, or preferably "3 phase H bridge" to get an idea on how the ESC works.
