Section 210.4 (C) Exception 2. Basically says you may use a MWBC for line to line loads IF you protect the circuit with a common trip double pole breaker.
I am a "working electrician" and this is definitely allowed... this is no different than a dryer or range circuit, which is a 120/240V MWBC!I have reread that exception and exception #1 about 3 or 4 times and do not believe the intent is to allow the use of multiple line to neutral and line to line loads on the same MWBC. Maybe we need input from one or more of the working electricians on this forum.
