I don't think it's delusional. The tech trees and how it plays with the map/your current game is huge. There are guidelines and milestones, as well as certain techs and civics you probably want to hit first, but the number of small decisions you can take and the impact it will have on your overall efficiency is huge... In Civ 5, once I knew which luxuries I had to improve first, I could probably tell you the exact order of almost all of my techs. Civ:BE was probably worst, because the illusion of choice there was much harsher once you started figuring out what techs you really needed.
The movement stuff, IMO they probably felt like the unstacking of the cities + active research were going to be such a huge step up in learning curve that when it came to combat they just went for minor changes and improvements, so he's just describing what they did that felt right. It's hard to argue that anything he says is wrong, for example, naval units stacking with embarked units is huge. It's just probably not what you are wanting to hear if you hated 1UPT from the start.
