NFHS Rule - False Double Foul

[bd41flpk]

Looking to validate an adjudication of this play: Rule 4-19.Art 9

1. A1 is fouled by B1 during a press
2. A1 takes exception to the foul and pushes B1
3. A1 is assessed a technical foul
4. As the players are milling about for :30 seconds, B2 taunts A2
5. B2 is then assessed a technical foul
6. POI: (as Team A is in the bonus) A1 shoots the 1:1 and the teams occupy the lane spaces
7. The two Technical fouls against A1 and B2 are considered a False Double Foul and no shots are taken for the Technicals

Thanks in advance for the ruling comments.
