Not so!,

During hot weather when the AC is in use the temperature control is usually
kept in the maximum cold position which closes the heater core
re-circulating door. When this door is closed air entering the lower plenum
chamber bypasses the heater core, therefore only unheated air will enter the
cabin.

In other words air conditioned cold air will still flow through the AC vents
into the cabin even if the hot water valve is wide open.
