If the memory wipe was all of Claire, would he remember his wife and family?  And as ClintMemo mentioned, what about all the people who knew her?
I wasn't thinking that Haitian Guy would go on a systematic 
Nowhere Man-style erasure campaign of Claire or anything.  Just that he would wipe Claire from Glasses Guy's (sorry, but I will 
always think of Bennett as Glasses Guy) memory, so that when he was later interrogated he could legitimately say, "No, I can't tell you anything about Claire's habits or personality or where she'd run to.  My wife says I have a daughter and I have to believe her, and it's bloody obvious what happened to me, but I honestly know 
nothing about her.  Can I go outside for my anxiety attack now?  Thank you."
But since I'm the only person who seems to have come to this conclusion, I have to assume it wasn't what the screenwriters meant to convey.  Alas.  I really think the show in my head was stronger.  >8->
