If the set ratios are the same, it doesn't matter anymore. We always check the set ratios first in PTS (for example, if the match would go to TB2, again we would check if the set ratio will decide the match and only after that we'll count the points).
The set ratios may be the same if they are both 4/5 and have a different match wrong. If you are going to check winner AND set ratio before doing the scoring for each TB, then you are right and it wouldn't need to be included.
I think we've sorted this

Thanks for fighting over TT with me and not stooping to personal insults
