By default, EF uses Change Tracking and uses an in-memory cache of all entities. You can use different Merge Options when working with EF. By default, EF 4.1 is set to AppendOnly Merge Option.

So you might be seeing the cached entity coming back.

In EF 4.1, you can use NoTracking Merge Option. This will go to the database for every call.
