The Megadrive pads need pin 5 of the pad connected for powering the multiplexer chip. If it works straight off, it's pin 5 that's powering it but that's not ideal, so it should really be connected to pin 7 on the Amiga.
Actually, thinking about that now, the fact that MD pads work without modification in 2-button mode sort of proves that pin 5 is held high by default, since it's this current sourcing that powers the multiplexer - otherwise it just wouldn't work...
