With my car if I try to charge and listen to my iPhone at the same time it causes a ground loop issue and the radio wont see the AUX input for a moment.
My understanding is there is a resistor doing the same thing for the aux loop so the head unit knows to post "aux" as an input option, but that its only 200mOhm, so not enough to trigger the cell phone to switch over the headphone output.
To answer your q, the cell phone stops playing. There seems to be an auto pause feature upon removal of a headset. This might be disable-able, but I like the feature for when I'm actually using headphones. I think the phone is programmed to update the headphone status between each song, hence without this mod, it senses an open loop and auto pauses.
