I suppose following the left hand imparts an extra level of accuracy.
No, it doesn't really. Imagine if you're at work and your boss is standing behind you, watching everything you do and instructing you in every little detail. That's how it feels for the hand you are watching and it certainly doesn't help. Besides, we use two hands to play and how about the other one? The hand you watch will always be a fraction slower than the other hand and that means they tend to go out of sync, reducing both precision and speed.
Can you refer me to the empirical data supporting these claims?
I surmise what he's saying is, we place LH fingers fraction of a second before plucking by RH fingers, which can't be the other way around. LH fingers before RH fingers, and never RH fingers before LH fingers which is quite obvious without any supporting empirical data.
The Boss example is to illustrate how our consciously trying to control based on visual input may affect our performance for the worse by extra steps on a side of more musical aspects in mind.
I would say, this one I would agree AND disagree. Upon our performance, we shouldn't, but for daily practice, we actually should better use the visual info, and we even use mirrors to have different viewpoints readily available in order for us to compare ours with our instructors or otherwise.
It's like we better practice parallel parking with mirrors available, and there is probably by far less point to practice parallel parking without seeing them or even with an eyemask on, and probably almost nobody would look at gas/brake pedals while doing so.
In fact, mirrors are must for flamenco guitarists when seriously practicing, but on stage they must be looking at dancers or singers almost 100% of time.
