On Nash equilibria and calculating EVs

[Ircher]

But 1/3 of the time, invoke the sacred Rule of First Voter Impunity: that whoever votes first is 100% cleared. Another way of stating this is that 1/3 of the time, the hammerer should vote for the person who voted first; but 2/3 of the time, the hammerer should vote for the person who crossvoted.

Pretty sure this is contradictory--the person who voted first is 100% cleared 1/3 of the time followed by you stating to vote the person who voted first 1/3 of the time.
