you are right except the credit should go to afld or specifically to their lab - lndd.
re. those new test, yeah, they play the game of cat and mouse alright but the uci is in the way. the way the business works is trhis, the uci doping control agent if instructed by the higher-ups will only mark a(the) specific test(s) on the doping control form for the lab to test for. the lab will just blindly execute the instructions, even if it's lndd
if there is a political agenda of not finding any positives, lance and the likes could dope all they want despite the test for abt (an example) being available.
