I'm not sure who was responsible, but, as I recall, the timing does point to a very good chance that it was simply a blunder that Mattel wanted to make look like it was intentional. I can see Matty, with Pee-Wee Herman's voice, saying, "I meant to do that!"
Regardless, I ignore the bios and a lot of the names, especially the "real" ones (I'm looking at you, Hector), so I don't really care much here. As long as we get a cool figure out of it, they can call him Tralfaz (yuck!) as far as I'm concerned.
