That is (famously) the Incredible Andrew Nicholson on the lovely Quimbo - be still my heart.
His round at Kentucky that year was spot on perfect and those shots of him doing drops at the Head of The Lake, etc. were the subject of a lot of amused adulation.
One comment: “I’m not that relaxed sitting in my recliner!”
Eventers have to be effective at riding over extreme terrain and tackle all sorts of different obstacles with different levels of balance and difficulty, different types of “questions”, at speed, and all the while staying in the middle of the horse so as not to disrupt their jump/balance - while varying between a soft and strong contact, staying behind the motion when necessary and slipping the reins, softly following, “steering” between the flags, and riding /adjusting the gallop.
I think it’s perfectly possible to ride a beautiful hunter round (and showcase the horse’s jump) without the excessive affectations, but then again, I did hunters in the 70s.
I do realize that most EQ horses have a flatter jump than most hunters, but don’t many jumper and EQ riders maintain good equitation - even when they ride hunters?
