Lockout = preventing the adjacent side from tuning on if one side is active, i.e. when the high side is active, the low side is locked out from turning on.
Not sure why you need the logic gates myself or how they would interfere with the differential signal, but personally I would leave the driver chip do it's thing and not add them on.
In order to use differential signalling, you'll need to have a diode across the inputs of InHS+ and InHS- and another on InLS+ and InLS-, hook the cathode side to the + and the anode to the -; this will cause the diode to be reverse biased when the other side is commanded on. Took me a while to wrap my brain around how this worked until I simulated it and saw the magic in action.
