Epilogue question (spoilers)

So I read both epilogues, and I feel a need to ask, is either one the "right" one? A lot of the other choose-your-own-adventure style bits in this series still eventually lead to one specific outcome. It wouldn't bother me, except that the implications behind each changes what actually happened in Ending Number Four. One implies that Jack lied in his blog, so the actual sequence of events before the decision has to be different between the different endings.

Am I misunderstanding something? Am I just a nitpciking ass hole for being bothered by this?
