Leaving Bench when fight may break out.

[referee99]

Gents,

Just trying to firm up my understanding of the penalties for players leaving the bench when a fight may break out, NFHS rules.

Sitch:
2nd half is about to start with throw in by Team B.
A1 and B1 do a double shove near division line,
A6, A7, A8, A9, & A10 come rushing in.
B6, B7, B8 come rushing in.

No fight. Indirects from actions of bench personnel cause coaches to both be ejected.
Intentional technicals on A1 & B1 for dead ball fouls.
Flagrant player technicals on the 8 who came on the court. All 8 team members from the bench are disqualified.
Differential from the two groups off the bench is a max of 2 free-throws. Team B will have 2 free-throws with the lane cleared and the ball for throw-in at the division line opposite the table. Team B keeps the arrow for A/P throw-in.
Team fouls for the half are now Team A: 6, and Team B: 4.

Just looking for confirmation that the penalty for team members leaving the bench when a fight may break out are flagrant player technicals and that each results in a team foul.

Do I have it right?
