HTC Droid Eris :: Actual Contact Moved To Recent Call List?

I personally own the Motorola Droid, But one one my customers has the eris. Here is the question. He claims that whenever he call a contact, the actual contact is no longer available in the contact list but is instead moved over to the recent calls list. I told him that I believe that the recent call list only shows recent call and that the contact should to be found in proper order on the Contact list. Having no actual experience with this phone, I'm just looking for clarification. Does a recently called contact have to be found in the recent call list? If not, what may my customer be confused by? Is there a free application to make this any easier for him?
