This results in a greatly increased stress on the structural integrity of the bottom of the lower vessel as the cooler upper vessel water is rapidly applied.  A loss of lower vessel structural integrity is a real probability.

Boiling water has a hard time making it over it's (adjusted for local air pressure) boiling point. If you don't let the bottom go dry, you're probably okay.
