Reversion is part of what causes it, so I'm sure the throttle plate actuation is a part of it, but I watched it live on my access port while driving yesterday. They don't stop their fuelling on decel, most likely. Your afr stays stoich or slightly rich the entire time it burbles and pops.
I ran an oversized exhaust on my ranger and got tons of reversion pops. This is not that. Also, they increase when you feather your throttle just enough to cause fuelling to occur.
I would also appreciate some insight from Stratified. I'm genuinely curious.
Edit: exactly. No "additional fuel". There are a few ways I can think of with timing and fuelling strategies that would make that work. Remember, Ford designed it to shut the injectors off completely on decel.
