I mean if you have a Charr warrior with a full legendary armor set, using the T3 Charr look... And you have it on your Asura warrior at the same time but it doesnt support different skins... You'd either end up with a very funny looking Asura, or a broken technical implementation. I am fairly confident Anet thought this out. That's the thing, we cannot equip an item that has a racial skin on a different race. The possibility of being able to have different sets of skins and dyes on a single piece of legendary equipment sounds great and ideal, but I doubt that would be their implementation - that's why I second the questions, so we could get some clarification on that. :)
