The Mechaber rules it is prohibited to reheat liquids that were cooled down below the temperature of יד סולדת בו
The Rema brings the opinion that אין בישול אחר בישול even by liquids but than rules that if the liquid cooled down entirely then it is forbidden

Major Question:
The Rema says that if the liquid did not cool down fully than it is permitted to be reheated.
Violation of cooking liquids is when the liquid reaches יד סולדת בו
Why should it matter if the liquid is still warm as long as it is under the temperature of יד סולדת בו it should be prohibited to reheat?
