There is a precedent for altering the box scores after a game. Bob Sura, for example:
Wikipedia wrote:With the Hawks, he gained attention by almost posting three straight triple-double games - the third was subsequently taken away from him by the league when he purposely missed a layup to get his 10th rebound. The NBA defines a field goal as attempting to put the basketball in the basket for a field goal. Since he had no intention to put the basketball in the basket, he could not be credited with a rebound.
Before Hakeem Olajuwon actually posted a quadruple-double, he had a near miss that Rockets officials felt should've achieved the mark:
Wikipedia wrote:Olajuwon was credited with 9 assists in the original box score. However, after Rockets officials reviewed the game tape and discovered what they believe was an uncredited assist in the first quarter, they revised the box score, crediting Olajuwon with 10 assists and the third quadruple-double in NBA history. NBA's director of operations, Rod Thorn, requested to review the tape. After reviewing the tape, the league disallowed Olajuwon's quadruple-double and announced that his original line—with 9 assists—is official.
With that in mind, if anything seems particularly questionable, I'd say the league does have grounds to investigate and take away stats that have been credited erroneously (or shall we say, "generously").
In Lonzo's case, I'd say on those two plays, he did get the John Stockton treatment.
