Bitplane dma can use "cycle 3". BUT blitter CAN'T use it.. (it becomes "8C" cycle again)
I think it's because the blitter has lower priority than the copper and the bitplane dma has the highest. That's why the copper can steal this cycle from the blitter.

The "blitter-nasty" mode keeps only the CPU off the bus, not the copper.
