Well, if by literal we mean something put in words, Pike was very clear about being very unclear.
"Mr. Saru, you have the Conn as Commander Burnham leads you through the wormhole. As to what happens after that... I would prefer if we focus on our respective tasks for now and discuss the captaincy later. There are many things to consider."
Why was Pike saying this stupid thing? Did he have some reason to oppose Saru as the CO? Earlier in the season, he was all about preserving Saru's status as Acting Captain, reducing himself to mere temporary mission boss.
Does he now have a hidden agenda that cannot proceed unless Saru is given the boot? Or did he change his mind when Saru had his radically altered?
