They were illegal.
Watch Royce Gracie-Keith Hackney from UFC 4. Kieth was in Gracies gaurd and Royce was delivering the same type of elbows on the base of Hackney head. Now that was legal in those days but when they showed that fight on UFC Unleashed it was explained that those where now illegal.
So yes, Lutter was screwed. A real shame just as he was starting to get out of the triangle.
