I assume it is another limitation caused by 68000/010 being internally pseudo 32-bit (all registers are 2x16, ALU is 16bit etc..) = Most 32-bit operations take longer than 8/16 bit operations.
68020+ are full 32-bit and shouldn't have these kind of restrictions. (But internal pipelining and buffering even when caches are disabled makes this kind of timing measuring really tricky if not impossible)
