Yes and even before Feldman Dusek mentioned it in his closing I posted here that it jumped out at me and I thought it was really odd.
It sounded very much like a man that was trying not to lie. You and I would have answered very clearly "Hey no way. Not me. I wasn't ever in that house."
This is as close to asking the question "Did you do it ?" that I can think of without asking. Anyone with an IQ greater that a turnup is going to realize that anything but a no answer is going to raise concern by the police.
At the time, how did he know they didn't have a print or something that tied him to the home ? If he simply answered no and their was some proof of his presence he would be caught lying. But if instead he answered in a way that leave the door open he could manufacture some excuse that he was in garage or something to borrow a tool or something.
