True only for resistive loads and loads of (approximately) equal
reactance.  But if, for example, one side is loaded purely inductively
and the other purely capacitively, the neutral will be carrying current
equal to the sum of the currents on the two hots.

(Of course, this is a contrived example.  Such loads are so unlikely
that I would expect even electrical codes, which are by nature
consevative about such things, to not specify a neutral heavier than
the hots.)
