But people who play coed volleyball usually do so under the special rules established for mixed-sex play that are meant to make the games fun and fair for all, whilst reducing the risk of injury to female players.
In co-ed VB, the same number of male and female players have to be on each side of the net, and male and female players are alternated in the rotation.
In "reverse coed" VB, the net is at the height used in women’s VB. Men can jump serve, but they're not allowed to block. Men are also prohibited from attacking the ball above the height of the net from in front of the attack line. Men can attack a ball that is above the height of the net from anywhere on the court, but the ball must take an immediate upward trajectory - they can't hit the ball horizontally or downward in part to eliminate the chance that they'll smash a female player in the face/head and hurt her.
In "regular coed" volleyball, the net is at the height used in men’s VB. If there's only one male player in the front row, then another single man may come from the back row to block, but not hit. If the ball is touched more than once on one side, then a female player must make one of the contacts. There are no blocking or attacking restrictions on female players - only on males.
That’s very different to what’s going on here. Blaire Fleming is a full-grown adult male who’s playing women’s NCAA volleyball under the rules for women’s single-sex play.
In all the women's games that Fleming plays in, all of Fleming's opponents are female.
