Put your Lance BS detector back on please! 

 You are being baffled by BS!
Anyone can state anything in a pleading, but you better support it with some type of authority even if secondary! It doesn't take much investigation to see that USADA has authority over him during the years in question and they have a right to arbitrate even on a non-analytical finding of doping. 
When you sign your license, it has an arbitration agreement, it doesn't say only positive findings of doping. It's all doping related matters. So in essence, going by Lance's logic he could have been trafficking in doping products, but hey, he wasn't tested positive. 
All matters of doping are adjudicated through arbitration per the license holder agreement with the issuer. With appeals going to CAS for final decision.
