Not testing positive as in antibody positive test. Positive as in re-infected, with symptoms.

Makes me wonder if they were truly recovered in the first place.

Correct. Virus tests.

This is why antibody testing is still unclear / inconclusive.

WHO has said that there is no solid evidence as to whether or not you can be re-infected. Seems as though it is likely that you can.

Also, there have been asymptomatic cases that tested positive twice - 24 days apart. This is a virus test. So, were they infected twice or did they carry (therefore potentially contagious) for 3+ weeks (in which case the 2 week quarantine is insufficient). Two independent studies (though one is Chinese) from February have shown this. The WHO still believes these to be re-infections, hence they have not changed their guidance (yet).
