Was this correct??

Held ball called, the arrow was pointing toward B, but given to A under B's basket. B's coach says something to official and they have a short discussion at the table.

A inbounds, goes up and scores a three.

Table sounds horn, officials gather and after a loooong discussion, give the ball back to B under their own basket. They at first removed the three points, but put them back on.

Was this handled correctly?
