Because machine learning isn't unheard of in compilers nowadays, it's perfectly possible some parts of the transpiler are essentially fixed function ... highly fit functions it will just readily drop in when it recognizes a trace of code which so happens to occur in geekbench and unlikely to ever be used any where else. Not so much in an intentional effort to mislead either, I mean why do it online when you can throw millions more cycles at it offline? Storage and bandwidth are cheap. Today geekbench, tomorrow Office.
