Apparently it can act counter to vitamin K at hypervitaminotic levels (and yes I probably just created a word).

I'm sure UpToDate probably has a good explanation.

I believe Goljan says Vit E has the same (or similar) mechanism as Warfarin

Vitamin E decreases clotting factors, especially in Vitamin K-deficient individuals, therefore compounding anticoagulant effects of warfarin. Exact mechanism is unknown.
