Both.
The drills are mostly there for improving overhead mobility, preparing you for C&J or even Dbl C&J.
The other pressing exercises are progressions for Single C&J, or for Double C&J for advanced lifters.
The TGU drills are specialized variety for grapplers and could be used one of your training days. (The TGU programming is very loose and the Swing programming very specific.)
But apart from that it is just Goblet Squats for the warm-up and Swings & Get-ups / C&J respectively for the training.
I have already incorporated some of the drills into my S&S practice. Can't believe I dismissed the Brettzel so far! It feels really good. Also, I sometimes replace a set of Goblet Squats with Long Push Presses. I intend to run the "Beginner to Intermediate" plan in the summer, given that I will have time for uninterrupted practice, as the sessions are timed. Contrary to S&S you just need one bell per session, so it would be easier to get my equipment outside
