Vs reverse?

I just finished perfecting my line ups but now notice that there is a vs reverse lhp/rhp and am a little confused.
Is there a strategy to these extra lineups? I understand it's say a left Handed pitcher who is better vs rhb but I'm just confused about how I can take advantage of this? Can some give me some advice on how to take advantage of this feature?

in a normal lineup it doesn't make much diference, I've never even used them.

If you were in a 200 mil ATGB league where your backups are 6 mil in value each, I could see taking advantage of this.

the problem is they brought them out as anything 1+, it should be like 5+ then it could be useful.
