For AC90 the inspector will ask you to read rule 12-608 for cable armor continuity and that it be mechanically continuous.
Then rule 12-610 sub-rule (3)for visibility of the bushing...Basicaly they will say it is contrary to these rules so its a defect.Almost the same deal for BX,thats how they rationalize it.
There is no a specific rule but these other rules dictate the installation requirements.
They do not want any of the conductor terminations to take the stress of the cable and should the armor become hot they want to be sure the OCPD clears the fault.
