Because if I've understood the code (big if ), the address should be ANDed with 0xfffffffc, not 0xffffffff, and the same applies for POKE.

You are right, it should've been ANDed with 0xfffffffc to protect from user error, but there's no need for safety guards because it's low level, reading from misaligned addresses will throw an exception, no big deal.
I may even remove those 2 commands once development is complete (which is a utopia, of course!!)
