Your example shows ambiguous markup that can be
interpreted in multiple ways:

1. <begin cell> \(<end cell><begin cell>x<end cell><begin cell>\) <end cell>
2. <begin cell> <begin latex>|x|<end latex> <end cell>

Org parser chooses one. It has to choose some.
Org parser also chooses a simpler interpretation that does not require
backtracking.

Yes, it is impossible. That's why I call it markup limitation.
We need to improve the markup to address this known problematic scenario.
