di doesn't; reading through the ports does.  You need to read keys through the ports if you're going to disable interrupts because rom getkey functions will no longer work.  The reason di will "disable" the on key is that the rom periodically checks for the on key being pressed during the interrupts, so if you make it stop checking for on, then it won't trigger any events that could screw up your program.
