I'm sure others can answer this better, but I don't think OIs change if you change a players position, they are set while playing a match and based on the opposition players position, not yours (I think). If you want to change them and save them you have to do it during a match though (save tactic after making changes while playing a match).
Finished my season with United, won everything with a squad that's far from reaching it's potential.
