Cheating In Galaxy of Heroes [MEGA]

Just to avoid any potential forum violations, I am not going to use specific names. But, can we get confirmation that the person who cheated on an alternative account was banned on his main account (on which he didn't cheat), but not on the alt account on which he cheated? Or were both accounts banned?

Ahnaldt101's video I think perfectly summarizes CG/EA's legal authority to ban the person, regardless on which user account they play the game.

But, if the alternative cheating account was not concurrently banned with the main non-cheating account, that would support the supposition that CG does not have the technology to detect the cheating as they apparently have not found the cheating account.
