How come Hb is denoted as a multiplet (triplet)

I understand that its near two unequivalent hydrogens and therefore complex splitting would occur. But, shouldnt it be multiplet (doublet of doublet)

I know for a fact when you're near two or three adjacent protons the n+1 rule applies only if they're all equivalent. But the two hydrogens near Hb are not =[

The answer says its a multiplet and therefore acknowledges that complex splitting occurs though.. maybe chad made a mistake?
