'Hide' hides the current tool window and restores the previous one, while 'Hide Side' hides all windows on this side. For example: Open the run window and then the debug window. If you select 'Hide' on the debug window, then you're back at the run window. But if you select 'Hide Side' on the debug window, then the run window is hidden also.
