Sarah:
I don't see a mistake here.  The reason is that it's an ongoing theme 
that Harry disagrees with pretty much everything Snape has to say on 
the subject of Defence.

In HBP, Harry disagrees with Snape on how to defend against 
dementors.  Like Harry, I had not realized there was even more than 
one possible strategy.

In OOTP, Harry never does manage to learn Occlumency, not that he 
tried very hard.  But Snape did not really explain very well what to 
do in a manner that either Harry or I could understand.  I would have 
been interested to see how the instruction methods might differ had 
anyone else attempted to teach Harry this.

I suppose it is characterization.  Snape is innately qualified to 
keep a classroom quiet, but he's no born educator.  The only time he 
manages to teach Harry anything at all is when he's not trying to.
