Taya responds:
I noticed this too. It happens a lot, until JKR reveals what 
something is, everyone calls it whatever Harry thinks it is. 
Once Harry finds out the proper name, everyone calls it that. 
I think it has to do with the fact that if HeRmione called 
them Dementors, Harry would then ask, what's a Dementor? 
And the reveal would be ruined IMO :)
