Electric/Gas Heat Pumps on Class A Discovery
While on a quick trip to Nebraska, we were using our heat pumps on "Electric" to heat the coach. At one point, the they quit blowing heat and started blowing cool air. They also automatically switch...

There's certainly a connection between switching to gas and blowing cold air when you're out of propane. There's no direct connection between running out of propane and the heat system switching to gas mode, which is to say running out of propane doesn't cause it to switch.
RV heat pumps typically don't operate at outside temperatures below something like 30 - 40 degrees, and automatically switch to using the furnace for heat at that point (or possibly electric resistance heat strips, if you have them on your units). If you don't have propane, the furnace clearly isn't going to produce heat.
Needless to say, the system operating on gas mode will use propane and so eventually cause it to run out if not refilled in due time.
