If you mean that the file state shows as recoverable, then don't read too much into it. Sometimes the file is marked as recoverable (as Piriform says) and contains rubbish. The test is whether what you recover is actually the original file.
Deleted files can also be overwritten with a valid live file. In this case the deleted file will show the contents of the live file, and if it's recovered the live file will be 'recovered'. This is a quite valid operation.
Do you mean that after a wipe free space you can still see the file names using Recuva? If so then this too is a valid operation, CC wipe free space does not (as far as I know) overwrite file names in the master file table. The test is whether what you recover is actually the original file.
