Maybe they're trying to write around the term "Coefficient of performance" (COP) for people who have never heard of heat pumps.

I think a COP of 2 at 5°F (-15°C) is pretty good.

COP of 2 at 5F is good. But... Mitsubishi has one that is 3.13 at 5F and LG has one at 2.65 at 5F, so this isn't really the breakthrough that the press release claims, the breakthrough is that a US company is doing it.

That depends on whether the Mitsubishi and LG units meet the other requirements of the competition.

Minimum COP for the competition is 2.1-2.4 at 5°F. No idea what the actual COP for this unit are.
