The typical period of infectiousness is days 3-10 after exposure.
So changing the quarantine recommendation from 14 days to 10 days makes sense.
7-10 days does not make as much sense.

Testing day 7 is hypothetically helpful, though imperfect with only ~75% sensitivity then. 
Still, most people in the US will not get test results back by day 10 even if tested day 7.
Hopefully this recommendation is used to further build the case for test results in <24 hours as being the only acceptable timeframe.

I’m not saying 7 days is wrong.
Just that it’s a bit more murky.
If I was quarantined I would not expose a vulnerable loved one until 10 days.
