It depends what bit you flip. If you flip a bit that contains the file type signature then Photorec verification will fail.
In a data recovery scenario where you are trying to verify files that were generated by filesystem reconstruction tools. You can open each file manually to verify if it is good or not. But that is very time consuming and inefficient if there are thousands of files to verify.
Using Photorec to automate the file verification process is not a perfect solution but it can be a useful tool to flag massively corrupt files which you sometimes see when filesystem reconstruction goes wrong and creates a file with the original file name and size but fills the file with wrong/corrupt data.
