Running blitter operation for each bitplane separately can be very ineffective, especially for small blits. Blitter has to be reprogrammed for each bitplane. Moreover it shortens time between consecutive calls WaitBlitter which does not permit for running computations in the meantime. All in all, potentially, lots of CPU cycles are wasted!
