I don't know, it looked like he was laughing at the fact that Light got her to trust him to the point to say her name the same as him(even saying the way it's spelt no less). But this is doubtable seeing how someone that smart wouldn't fall into that so easily(Although, Light is a genius, so pretty much anything is possible up to this point).
