yes, and yes. anubias has a hard time transitioning from wet to dry, but not so much the other way. I've heard of ppl complaining about their anubias "melted" when they put them into their tank but I've never actually experienced that. I think it's mostly exaggerated, and they just wanted to blame something. you can put it back and it should pick back up quickly. to move them to emerged conditions, you want to do it slowly.
