How is that a negative? It was still an OT win - it just goes to show the strength of Russia's defense, if anything, imho.
It was also possibly seen as, overall, a stronger group?
Two of the top four seeds are from Group A, after all.
Based on outcomes alone, Finland might have gotten robbed with a lower seed. They won 2 outright, and lost in an OT - Russia only won one outright and needed an OT win, and also had their only loss in OT.
There's more to it than looking for cut and dry results based upon outcomes.
