Question About B757 Spoilers

I was watching a YouTube video, below, that featured a 752 landing at LGA. If you watch between 37 seconds and 40 seconds, you will see the spoilers retract slightly and go back to full deployment. I've actually noticed this on my flights on 757s before too. I'm trying to think why that would happen, but being not technically literate as such I would rather ask here. I was thinking along the lines of either the deactivation of the autobrake system to go to manual braking, or the reverse thrust system being taken off. Anyone with insight?

Nothing to do with aircraft braking, nor reverse thrust.
Those spoilers are dual purpose, ground spoilers deployed after landing AND differential spoilers, for roll control assist.
Very similar to those spoilers on the later models of the B707.

What you saw with the slight retraction then reextension of the spoilers is most likely the technique this Pilot used to disengage the autobrakes.



This method, slightly retracting the spoilers will give you a nice smooth autobrake disengagement, which can be tricky to do by just pressing the footbrakes
