Cool video Bonner.
Don't take this as an insult, I still think you need to get out on those tips man. Work order said "prune for structure".. You saw the tree close up, I just watched a video..... looks like some potential V crotches and issues in the future just looking briefly at the trunk.
When my work order says "crown reduction" I'm focused alot around the outer crown, maybe taking 2-3 foot lenghts if that.
When My work order says " Thin (say) 10 -15 % and prune for structure" I still go out to that outer crown and thin just the same as would the inner. Expecially with those nursery variety Maples...Loaded with V crotches and poor structure.
