Sled GPP

I just started into a Westside program but I’m a little confused about the sled protocols. I know that most of the sessions should be light with an emphasis on restoration, but when I drag heavy on the ME/DE squat days should those sessions take place during the workout or a few hours later?
THanks

do the heavy sled work out for max eff during the workout…as the 2nd movement…bm
