While it may look similar (because only horizontal scaling was done), I don't think the output was identical. Both scaling and deinterlacing cannot be undone and do have an impact on quality (if you define quality as identity with a - possibly hypothetical - original). I can understand why you want to deinterlace, you should avoid the scaling (unless I miss something and you absolutely have to do it).
