Yep I believe Clark said that knowing Lois as the Blur made him see a whole different sie of Lois that made him for much deeper. In season 8 we saw Clark's feelings for Lois but he was so oblvious of it which was why the quote, "How could a guy with x-ray vision be so blind." was perfect for Clark.
It's one of the reasons I can excuse Clark's bad decision making in season 8 when Lana returned, Clark settled into something that was safe... and he didn't know what his feelings for Lois was at that point... same when he rejected the dinner date, he wasn't ready to take that step.
