Potioncat:
It appears to me that the usual method would be to place the memories 
into the Pensieve for a brief period of time and then to return them to 
your head. DD was taking thoughts out to see if they formed a pattern.

Snape appeared to be taking thoughts out to keep them from Potter. In 
each case, Snape waits till the last minute to remove them, then 
replaces them as soon as possible. Many readers seem to think it was 
his way of taunting Potter, but I think it was standard procedure.
