That might be why swapping the battery fixes the gremlins, you're effectively resetting the system but the throttle trick is a built in reset you can do whenever you feel like it.
I think what you are actually doing is resetting the throttle idle point. Mine often fails to run correctly/stalls and over time it seems to be caused by the throttle not being in its normal rest position when starting the engine or starting the engine too quickly after putting on ignition and not allowing the throttle to reset itself correctly.
In my case, sometimes I forget to unscrew the throttle lock when I stop the bike.

Opening the throttle as you describe simply has the effect of ensuring the throttle is in its correct position when you turn the ignition on the next time so allowing the bike to correctly set that as the idle position.
