I believe the referenced "lying" is not in the call, but when afterwards he claimed internally that the incorrect understanding was the true one.

Days afterward, spez got on a conference call and falsely claimed that Christian was blackmailing him. An employee of Reddit itself affirmed that he said it in a summary of the call they posted to a (private) sub of high-level moderators, replicated here:

(The summary in the main thread was written by members of the community on the call, the comment I linked is Reddit’s own summary.)
Reddit has also repeated the same claim off-the-record to multiple journalists.
Him and Spez (or whatever his name is) got together in a tense meeting on two opposing sides, there was a failure of communication (like in many such cases), things escalated for a bit after that but, in the end, I see that Spez recognised that he had understood things in an incorrect manner. That is I see no deliberate "lying" coming from the reddit CEO.
