Good question.I know in highschool we use to say ice made things colder. The prof would say it absorbs heat.
Well for a while as it opens it introduces cold coolant from parts of the car it was not circulated through like the block,heater core, then radiator. Then as those start to warm they radiate heat and provide more cooling.
Owning a scan gauge is fun to watch water temp. I use to dirve from a dead stop 43 miles. I notice I never got to operating temp but it constantly went up and down. If I got a stop light, just one. I would achieve operating temp and it would only go down maybe 3 degrees the rest of the trip.
Furthermore when I am in traffic I see up to 203 when the low speed fan kicks on. Once it seems heat soaked I never see it go below 185 for duration of that trip. .
