Yeah, I understand your first sentence, but the last part of their comment was

"Plus, a horizontal fridge is just… convenient. You can’t even put things on top of a vertical fridge."

Don't they mean a horizontal fridge is a chest fridge? Which would make it sound like they want their whole comment to be in support of a chest fridge? Which is why none of it makes any sense to me.

That's what makes me think they've simply mixed up horizontal and vertical, because you can't (conveniently) store things on top of a chest fridge, but you can store things on top of a vertical fridge. Basically I think they've got a coherent point if you swap vertical and horizontal throughout their whole comment.
