Am I missing the usefulness of this or is it a bug or is just that the enter buttons needs to do something?

Try something more interesting than a static expression, perhaps something like Ans*1.1 or 1/RANDOM. Whatever expression you type gets re-executed every time you press Enter, so the result can change with each press.

Tangentially related warning about Ans: In Home, Ans will always equal the result most recently calculated in Home, even if you have deleted it from the history. In CAS, however, Ans is always equal to the bottom-most history item, regardless of whether it is the most recent result or not. So deleting the bottom item usually changes Ans in CAS but never changes it in Home. This is not documented anywhere, so keep it in mind when you use Ans or you'll get unexpected results.
