I'm pretty confused, what is this?

Soo, a friend of mine from Ragnaros can seduce through spell reflect, why does this happen? We tested with other warlocks and seduce gets reflected just fine.
Yesterday I found another warlock who can seduce through spell reflect, but these people are quite rare, everyone's else seduce gets reflected.

Please move it in the appropriate section if I posted this in the wrong place.
