Russia has continued to obstruct the investigation and it was only mid-November when WADA determined that RUSADA was still not compliant with the specifications:
"Those included Russia’s continued denial of the findings of a WADA-commissioned investigation that showed systemic and state-sponsored doping in the country; that the Russian government has not yet released electronic data and samples from the Moscow laboratory; that doping control officers be able to access Russian athletes training in closed cities for testing; and that RUSADA correct non-conformities found in a WADA audit.
“For these reasons, the CRC unanimously maintains its recommendation to the WADA Foundation Board that RUSADA should not be reinstated to the list of Code-compliant Signatories unless and until these remaining issues have been fully and satisfactorily resolved,” Jonathan Taylor, chair of the compliance review committee, wrote to Niggli on Friday."

I doubt that the uninvited skaters were simply picked randomly. I'd like to know more, and I certainly hope that the athletes get some more information.
It probably would have been cleaner for the IOC to have simply banned participation in this Olympics for any Russian athletes who competed in Sochi, or even for the entire team. Harsh, but given the continued (and ridiculous) denials of state sponsored doping at this stage, better for eventual clean sport. Unfortunately, the IOC spent entirely too much time diddling around and this has all transpired far too late. Better for Russia and Russian athletes to have been told last August that they weren't going to compete. The International Weightlifting Federation didn't have a problem banning Russia and Bulgaria from weightlifting in Rio, and a bunch of other countries were banned from participation in the sport for a year.
Dropping this hammer on two figure skaters at this point in the season is unfortunate. I hope more information is released.
