Regen after battery is fully charged

I recently fully charged my Volt at a relatively high elevation. After it was charged I proceeded to drive downhill, which resulted in the Volt attempting to regen some power back into the batteries. But since the batteries were already fully charged it appeared to switch to gas mode and started logging gas miles. Except that the ICE was not running and the Volt still appeared to be in 100% electric mode. What was the Volt doing? Is this how it handles a situation where the batteries cannot accept further charging? If so, where was the regen power going? Were the brake pads possibly being used instead of regen without my knowledge?

I have a 2015 Gen 1 Volt.

It is running the two electric motors against each other to simulate regen. In the Gen 1 models, there is a bug in the software that causes it to record it as gas miles even though the ICE is not running and no gas is used. I would see this all the time in my 2013, however now in my 2017 I have not seen this happen yet. They must have squashed that bug for Gen 2.
