Again, do you want to say that if Allomere punished (fine/ban) Fal'Cie for expressing his intent to disobey, then it would be OK... but to give him the final chance to reconsider (reminding him that he will be fined/baned if he realy disobey) - that was the violation of the rule?
If Allomere had instead simply reiterated the order, and added, "and if you don't, there will be consequences," that would have been fine.
The problem is, he said, "and if you don't
by tonight, there will be consequences." That's not fine.
You're acting like there's only one possible way for Allomere to have given Fal'Cie one last chance. It's simply not true.
