My guess is that using his Tomoerinnegan/EMS combo allows him to search out dimensions but it costs a lot of chakra to do so. My guess is that he was recharging his chakra so that he can use it again and make a SP/T jump or something.

TLDR: He has access to his full power but only for a certain amount of times per day.
