If a person is shedding the virus for 14 days after the symptoms have finished then why does the cdc recommend that they don’t need to quarantine, shouldn’t they be considered contagious?

14 days is the 99 percentile for incubation time, with 5 days as the average.  This is time to show symptoms after catching the virus.  This is where the 2 weeks recommendation time comes from.

This is not the same as post infection contagious period which is 9 days from the start of symptoms for all cases that aren't bad enough to require hospitalization.
