Yes it can.
Make sure when you screw the mouthpiece you dont tighten it too much, that is the main reason your atty is getting unscrewed. Just give it a tiny little extra turn when it gets slightly tight.
If the atty gets flooded i close the liquid control, and blow through the mouthpiece, this will push excess juice into the collector below. The way the collector is designed with 4 holes, you can still vape with that juice down there just fine, if you get a bit dry give it a strong pull and it will pull that juice down there into the atty so you can vape it all that way. Then reopen the liquid control slightly and continue to vape.
