Reversal of warfarin, effect of IV or oral vitamin K?

I know that you can use Vitamin K to reverse the effects of Warfarin and this will help normalise the INR. I have heard that IV Vitamin K makes the subsequent stabilisation of INR more difficult if Warfarin is recommenced, and that oral Vitamin K will mean that, if Warfarin is subsequently restarted, it will be stabilised more easily. Is this people's experience and does anyone know why this is the case or what the evidence is of this?
