I don’t think Quirrell’s model of emotions can be all that refined, since he seems to have repeatedly and legitimately mismodelled both Harry (“yes, I actually do care about people even if I don’t relate to them, I don’t want to be a Dark Lord,”) and Hermione (“You know, a shadowy figure in a hooded cloak is really not the most trustworthy messenger.”)
Obligatory protest that we don’t know for certain Mr. Hat-and-Cloak is Quirrell.
The way I interpreted that, he thought that if he first showed up looking innocent and good, she would have suspected that the outside was a sham. But after she revealed that she really doesn’t think that outsides are always deceptive, he changed his modeling.
Though that would still mean that he mismodeled her, yes.
My thoughts on the mismodelling* of Harry are much more speculative.
