Illegal substitution?

with five (of the eight on-court) players from Team A and three players from Team
B involved. RULING: Substitutes become players when they legally enter the
court; in this case, when the official beckoned them onto the court. The players
being replaced by A6, A7 and A8 were not known at the time of the fight to determine
what players would be classified as "bench personnel." The officials and
scorer shall make an effort to determine who substitutes A6, A7 and A8 were
replacing when the fight broke out. If the players being replaced by the substitutes
cannot be determined, the only recourse the officials have to determine
what penalties to assess the head coach for the involvement of bench personnel
is to assess the maximum penalty. Of the five Team A players involved, assume
three were bench personnel and assess three indirect technical fouls to the head
coach, which results in ejection. Team B would also be awarded four free throws
(two for each additional player involved in the fight). All participants are disqualified
for flagrant fouls. Play would be resumed with a Team B throw-in from the
division line opposite the scorer's table. (10-3-9 Penalty; 10-4-1h Penalty; 2-3)

Wow thank you for typing that out. I wasn't willing to do that. The RULING section is what is leading me apparently astray. Especially the last half of the first sentence.
"In this case, when the official beckoned them onto the court."
