But Merlot is a man of science. Due to this, I imagine he would go for a rarer and non-religious usage of the word netherworld.

Or his fascination with the Grimm caused him to look into the occult and that led him to believe they were not from this world. I can see him using netherworld to decribe it even if they weren't from hell or something similar due to him presuming that any location these creatures originate from has to be hellish.
