I guess a better translation is "He isn't that, he is like that." But I agree that English doesn't have a distinction between permanent states vs impermanent states in the "to be" verb.

Probably 'He isn't always like that, he's just being like that".

"He is not like that, he is only acting like that" or "He is not like that, he is only currently like that."
