I do'nt know exactly the rule in this case, but here after the first sample, just one technical fault in second test can save him!
The first sample was positiv, the second should be too, there is no technical reason to failed it, only bad procedure...
So if it will happened, it will be a bad chance for cyclism, because FL were on paper "not guilty", but technical guilty and fans will be "lost" again.
(FL knows that)
Now if he can prove (like very very difficult too) that his body can product this T, but that is no the question.
It will be better to have just one sample for this case, less ambiguous for all (riders, cyclist, and press).
