So simple ... thanks you !

There's a gem pair that precedes the 0G RRA gem move: BB LL

This pair pushes the 2nd column above the top line, thereby terminating the game.

I don't understand the rule for this (9th of the Fixed test)

32 th move

   ___ __
 0|      |
 1| Y    |
 2| RR   |
 3| RY   |
 4| BB   |
 5| BB   |
 6| rY y |
 7| GB BG|
 8|GGBYYY|
 9|RGGYGY|
10|BGGGGG|
11|YY GGG|
   ------


-Move 33 =>  0G RRA

   ___ __
 0|      |
 1| Y    |
 2| RR   |
 3| RY   |
 4| BB   |
 5| BB   |
 6| rY y |
 7| GB BG|
 8|GGBYYY|
 9|RGGYGY|
10|BGGGGG|
11|YY GGG|
   ------

The expected result is like if the move 33 was canceled.
But i not understant why (which rules applied here ?)

"If at any point in the game a stack of Gems goes above the top row, terminate the process and return the game state before the last move. This applies to Crash Gems and Rainbow Gems as well; their position is taken into account before their effect."

But the stack of Gems goes never above the top row
