Ford has been doing this for decades (I think I saw it mentioned in the docs for EEC IV.) It turns off fuel for a cylinder here and there intending to pump heat out of the engine (a cylinder with no fuel is an air pump.) It doesn't really let you operate with no coolant. Might get you farther before you die if you push it.

You are correct, that the manual doesn't specifically say it can operate without coolant (now that I re-read it). What it does is active fail safe mode, then will shut the engine off once the temperature goes above another (higher) threshold. So I guess if coolant is completely gone (instead of just low), you may be able to drive for a few minutes then be shut down for a while before driving again (the main purpose is to give you enough time to find a safe spot to stop).
