These both appear to perform the same action 'displaying the toolbar & 'topbar' - sorry not quite familiar with all the ui component names yet'...
This seems like the waste of a valuable edge, how about making one or the other user definable, for example i'd quite like
Swipe down - current system default
Swipe up - display virtual keyboard
This ide is shamelessly borrowed for how a certain other OS allows you to redefine (within limits) the action performed by moving the cursor into one of the 'hot corners'
