Electric water heater getting 120V to ground on each feed but 0V between them. Bad breaker?

If one leg were open, wouldn't I get a reading of 0V for that wire

Think of it as a voltage divider circuit. you've got 115 volts
going into a 15 ohm resistor going to a 20 Kohm analog
meter to ground. voltage would barely drop aacross the
hw heater element.
