If the bypass doesn't start to close above approx 80, then coolant will continue to circulate in the block and bypass the radiator. The bypass is supposed to fully close above 94. The main is supposed to open at 80.
The lower hose never gets warm with a thermostat installed. I can't say that I've ever felt it without a thermostat.

From your last part of your post I don't think I fully understand this cooling system. Are you saying that there are 2 valves in the system? One being the thermostat and the other one being what? Where?
