Most parties are aware of this and will do their very best to avoid going down that road, the few idiots that don't usually end up in a bad way though some may get lucky.
Cutting down the fluff you've just confirmed what I said. Basically when it does not cross into legal criminal fraud as defined by law you can't call it a fraud. Same as with taxes, especially corporate. One can be and idiot, creative, fraudster. The middle one is subject to interpretation and the amount of money involved. "Doing very best" does not necessarily mean not lying.
You can see this happen every day, plenty of cases that are fairly obviously - to a layperson - fraud end up not being prosecuted because it is hard to prove the facts and then there is the matter of intent. Still, nobody is fooled.
I hold myself to a far higher standard than my former employers.
