This makes sense to me. It sounded to me like they were both coughing at first but that Saul ended up growing accustomed to the air quality. If that's the case, I don't see why he couldn't go back in. However, it might end up being bad for him over long periods of time so this would be a gamble.

Personally, I expected when they pulled the camera up out from the crack for there to be something insane / creepy / gross down there.
I had thought that about Saul at first as well. However, it's possible he was reacting the way he thought he would to being without oxygen. Sort of getting a placebo but being told it's Valium. You feel the effects you think you're going to. Or you may be right. He may have simply acclimatized.
