For combo boxes surely, otherwise I would say no or not always. 
(Moreover NeXT UI guidelines state scroller must be on the left)

When I corrected NSComboBoxCell implementation, I decided to keep it 
like that because scroller is on the left with GNUstep (not on the 
right like Cocoa) and it looks like poorly designed UI in my opinion 
when popup list extends below combo box button. Well I admit I'm not 
very satisfied by the current choice, I have even thought to put this 
button on the left of the text field but it looks worst.
