>Circuit breakers prevent that from ever happening.

except there are no circuit breakers on the neutrals. see pic.

what actually happens, as mentioned in >>806040, is that the two loads are effectively put in series across the 240V lines, and if they're of diff wattages, the neutral takes away any excess current so that they each have exactly 120V each.

e.g. two loads of 10A and 8A wont put 18A on the neutral, only 2A. coz math.
