If the two 30 amp outlets are both wired to the same phase, that will also work with one caveat. If both 30 amp legs were loaded to or near maximum current, you could possibly run more than 50 amps thru the neutral wire that is sized for 50 amps.

So on a standard 50A plug and service, isn't there still only 1 neutral wire and would have the same problem?
