exactly 1 XInput device with A down (#1), and incorrectly correlate. This code will then un-correlate
when A is released from either controller #1 or #5.
B) Since the app may not open all controllers, we could have a similar situation where only controller #5
is opened, and the user holds A on controllers #1 and #5 simultaneously - again we see only 1 controller
with A down and 1 XInput device with A down, and incorrectly correlate. This should be very unusual
(only when apps do not open all controllers, yet are listening to Guide button presses, yet
for some reason want to ignore guide button presses on the un-opened controllers, yet users are
pressing buttons on the unopened controllers), and will resolve itself when either button is released
