Let's assume for a moment that alexg is not a moron. If that is the case, he already knew what it meant that she left the stuff.
Now, if you already know it and aren't happy with it, you won't post about it in a "what would it mean?"-way. You post about it in an "aw shit I'm in trouble"-way.
However, on the other hand, if you're hoping that she meant what she meant, you might want to see your hopes confirmed. New lovers are insecure, after all. In fact, you might just post about it simply out of happiness about the new relationship.
So, here's what I think: alexg is in fact not completely clueless when it comes to women, is at the moment really happy and excited about what happened, and is pretending ignorance in an attempt to look cool on GFY.
