It probably could, though Maedhros was usualy pretty good at feeling such things out much faster than this. Apparances didn't often fool him and he is going to be kicking himself for this massive slip up for quite some time to come.

Thankfully the demon didn't exactly seem inclined to hurt him, has even been somewhat polite even. He was very confusing to the poor elf who simply inclined his head politely in return. "I wish you luck on your hunt," he says weakly as an afterthought.

Maedhros was certainly thankful he didn't have to see what came next, he hadn't really wanted to see or hear what he already had, but... he was also somewhat thankful for the demons intervention. It might not have been an altruistic act on his part, but it had been helpful nonetheless.
