Kinda. The exact quote for it being lowered down without heating up from reentry is "the added ice would cool the water down by only about a millionth of a degree" But yea essentially useless in the big scheme of things.

The ice would be massively better used in space habitats or terraforming other places.

You stopped reading too soon:

Unfortunately, comets would affect the Earth's temperature in another way. In addition to dust and water, they contain a small amount of CO2, which would be released into the atmosphere as the comet melted. This CO2 would change Earth's radiation balance

Right you are I missed that. So comets at least aren't workable.
