Sometimes the flaws in non-standard calls are only obvious after the accident. The "put it in" guy might have been saying words to that effect for years with no confusion.
My opinion is that if there is a standard callout appropriate to the situation then that is what you say. If there is no applicable callout, then don't be afraid to use plain language to get your point across.
Someone else made the comment that the regulator must be pretty uptight to pick on your use of standard callouts, another viewpoint might be that your use of standard callouts is so poor that it genuinely needs to be fixed.
