They finished fourth. Only 3 couples go. The Russian federation will more often than not go with the podium finish at Nationals to go to Euros, unless a top skater missed nationals for some reason or, in the case of Kovtun in 2013, someone whines enough that the fourth or fifth place finisher needs experience or would do better. Why would the federation remove a couple who finished third at Nationals and has the TES minimums for both the SD and FD for a couple who doesn't?
I see. Thank you for the clarification.
