The fine is referring to this moment in Game 5 where Les Alexander walked out on the floor while the clock was running and spoke to the referee.

Les Alexander has been the Rockets owner since 1983, so I’m sure he has a lot of strong feelings about his team. But you can’t be walking down to the court like that.
