It’s usually if you have the valves open first, then open the tank into the empty line you can trip the high flow switch. It’s designed so that if there is no back pressure in the system to stop flow. Usually the Jet nozzle is sufficiently small to provide that back pressure but the speed of filling the empty line can trip it.
For that hose explosion I would suspect a regulator issue becuase thermally expanding gas under ounces of pressure shouldn’t be enough pressure to split the hose. I would suspect that the hose pressurized up to the boiling pressure and the propane was liquid in the hose. Then thermal expansion from liquid blew the line. That would only happen though with a malfunctioning regulator.
