Yes, that term also means one way, but it is no uncommon for a language to have multiple terms that shares a similar meaning. But if you wanted to be really specific on their usage differences (which I don't recommend in doing, I prefer leaving the range of a term's range of interpretation to its broadest) In 片道's case, it is used more to describe an actual location that you can only travel one way.

I wonder if he can turn invisible using that field. Just ghost in and nuke the opposition

Spoiler:

He turn invisible is enterialy possible, consider he indeed has the power to manipulate light and other radioactive waves.
Teleportation would certainly be effective, but I wouldn't say it is practical. As you have to aim for a specific location on the body for that to work. And he has some many ways to disrupt the aim with his power. The ability to phase through matter also wouldn't work, consider his reflection field isn't totally physical to begin with.
