It's not inconceivable, but between the second screenshot being almost certainly in Firebase Goddess, the krogan in it looking like a possible MP character, and the fact that every indication about the SP DLC so far suggesting it's going to be focused on the Citadel (including the first screenshot), I would be very surprised if the second isn't for a separate MP DLC.
