You have to account for the pitcher's splits as well.
Generally, pitchers are rated better against batters from the same side (so the RH P will generally have a higher vsRH split).
If, though, the RH pitcher in question has a vsRH of 50 and a vsLH of 50, then the batters with the same 60VSR should match up equally.
