Actually he is not lying - he is accurate in saying - P2b data is unblinded - he does not have P data
He never said he has not seen interim data. He never said interim analysis was not done. He just said that interim data will not be released - that could mean that he actually saw the data and was not impressed with it and decided not to share.
That happened in Dec 2017 and his focus changed and his PRs are on B.
In short, he is not lying but more than likely he has seen interim results.
