Where did you hear that?  I've heard Theymos refer to Lauda as "he" before, and Theymos probably knows what gender Lauda is. 

And no, I don't think those two are the same person.  I'm starting to think Foxpup is Theymos, actually--don't ask me why; it could be that I've had a nitrous oxide leak in my house.  I never rule out that possibility when I get strange associations.
