I believe between the top and the AC unit there should be an AC gasket and that's all you need. Maybe someone thought it was leaking???

I would not caulk buttom unless it was leaking. Too easy to leave some old caulk and make a leak. Top I would put a new gasket on if it leaked. Caulk property applied is good for 20+ years.
