I have no idea. Marvel's been really skittish about showing any signs of affection between homosexual couples. It might be their way of finding out if their customer base is willing to accept it.

Or it could be they're really skittish about it and want to be able to point to something and say, "See! This is why we haven't done this! Nobody wants it!"

...

Both of which are dumb, yes. I have no idea.
