It most definitely works, and works well. The worm gears do make things a little tricky, for instance you really do want to make sure that you have both motors turning in the correct direction before you connect them together, and it can be a bit awkward to get them both precisely aligned onto a keyway at the same time.

It can be done... it is just a bit trickier than using, say, two globe motors that you can backdrive relatively easily.... and you really, REALLY should make sure that both motors are turning and in the correct direction before you tie them together. Yeah, I know I mentioned that twice. It kind of matters.

Once you've got them set up, though... it should work like a charm.
