Sure it wasn't dirty, but it wasn't fully clean either. A clean win is when wrestler A pins wrestler B by their own athletic ability. Wrestler B being taken out by injury, sickness or some other non typical fashion (Angleslam on Sunday knocking Angle out, Triuple H getting a concussion from Axel) is still a protected finish and somewhat murky. Roode went over semi-clean.Roode didn't use anything illegal nor any other illegal activities to score that pinfall, so yeah, he went over cleanly.
