This is just the way he is now again, evil and four armed, like in the movie. Redemption might as well have not happened, because not much would be different if he died at the end of Season 2. For all we know he could just be lying, after all he sort of implied he will not come back in S8 and yet he did. Whenever he was asked about Garmadon returning, he either said "Garmadon is dead" or "Garmadon is in the Departed Realm". Which was true, he just came back to life. It's not a straight answer to the question.

This:

A: "Is Sensei Garmadon returning?"

B: "No plans."

..is as straight as you can get. No plans means no plans. If a year before SoG came out, he said that about Garmadon returning, he'd be lying, SoG was being written at the time. If three years before SoG came out he said that, he'd be telling the truth, there was no plans to bring him back at the time.
