That sounds dangerous. Is it code?

Yes it is. Fairly common actually.

My disposal is socketed, not hardwired, which is my preference for safety.
If I stick with 5-20 sockets, this Edison circuit could concievably put 240v
across one of them. If I use 6-20 plugs, someone someday might think it's
OK to put 240v across a 120v disposal motor. Either way, not good.

The only difference is that only one neutral wire is used, instead of
two. You still use the same socket, just break the tie bar between the
two hots in the socket.

Using a tied breaker will make it obvious what is going on, as well as
safer, with one breaker to shut off both disposals.
