Another FT situation

[Nevadaref]

We both know that the NFHS doesn't do a great job of making things clear. It does give us something to complain about, though!
As for why the case play is not labelled with a 9, the best answer that I can give you is that it is not a technical foul to fail to comply with 9-1-2. There is actually no penalty at all for this.
However, it IS a technical foul for a team to delay the game 10-1-5b, and that is the pith of the situation.

I know that seems like splitting hairs. Yet it is true.

For an analogous example, allow me to recall the situation in the ACC tournament game between Maryland and NC State in which NC State was charged with a technical foul because a manager was wiping up the floor following a time-out. They had done this before in the game and were verbally warned by the official. There is certainly no rule against this.
Strictly speaking the T was not for spilling water on the floor, or getting sweat on it during the TO, or even the act of wiping the floor, but simply for delaying the game.
