an SGA question

So when Rodney says to Teyla that he has encountered not one, but two different versions of himself, which are the ones he means? Obviously one is "Rod" from McKay and Mrs. Miller, but which is the other alternate self he has met? I mean, iirc the one in the timeline from Before I Sleep just died and he was told about it by Elizabeth, and I don't recall Rodney meeting his other self in Moebius nor during The Road Not Taken either? Or did he? Argh, my memory is like a sieve.
