As others have said that is the tool and right is left and left is right.
Plastic cups work fine if you aren't a klutz with tools. Trying to replace a plastic cup with a metal one might create issues.
In my Ti MTB I've had a cheap BB with two plastic cups for a couple decades. Completely proof against galvanic corrosion.
