Mir had a myriad of excuses outlined in this bloodyelbow article below. The main difference is even if Mir got caught with something he took long ago he still has to be suspended because he tested positive. Jones got suspended and already served it.

One thing interesting in this old article:
"This is an interesting one. The idea of finding out when you failed the test in order to narrow down which supplements to have tested for contamination is a good one. As a result, I asked USADA if Mir ever requested that they go back and retest even older samples to try to find out what the first instance of the metabolite showing up was. By doing this Mir could easily narrow down which supplements to test.
USADA spokesman Ryan Madden informed me that Mir did not, at any point, request that previous samples be re-tested."
