Hidden Panda on SSC floor

Astela on Maelstrom sent us this shot of the floor in Morogrim Tidewalker's room in Serpentshrine Cavern. It took me a second to see it, but right there in the designs on the floor, you can see a Panda, calling card of one Samwise Didier, one of Blizzard's lead developers (and lead singer of L70ETC).

He's also the creators of the fan favorite Azerothian race we haven't seen in Azeroth yet, the Pandaren (I'm a little disappointed that they didn't show up during Brewfest, actually). Obviously, this is just a hidden Easter Egg done by one of the artists, right? Clearly, this isn't proof that the Pandaren helped build the Coilfang Reservoir or anything like that. Right?

Thanks, Astela!
