I originally read this as an attempt to obscure the sexual violence implicit in the older half-orc lore, rather than to emphasize it more strongly. Mainly due to "crossbreed," which doesn't necessarily imply force. Not discounting your take; just an alternate perspective.
That said, I'm of the opinion that half-orcs should just be retired as a character option, in favor of featuring orcs as a core option, as I'm not sure that older-edition baggage can ever fully be shed otherwise. (Or at least, have both orcs and half-orcs, and treat them akin to elves and half-elves.)
I'm leaning towards wizards retiring all "half-" races. 4e did that for a number of them (which is why we have dragonborn and not half-dragons, and tieflings having a mono-look and origin). The only issue I see it is it would royally screw up the dragonmarked houses of Eberron...
