The water is the excuse for an "Italian tune up", not the
reason. :-) Others include "carbon on the valves" and the ever
popular "carbon on the spark plugs".
The emulsified water in the bottom of the pan isn't substantially
reduced at high temperature, but condensation that forms inside the
engine when it's shut down will evaporate if the engine comes up to
full operating temperature and remains there for a while. Repeated
short trips that never get the temperature up will cause more water to
accumulate. I've seen huge amounts of oil pan water accumulation in
vehicles that were operated without a thermostat in the cooling system.
