That may in some ways be intentional.
Don't forget, Win and Paul know their stuff, and everything in the course is for a reason.
My reason fro why he says "don't sneak a peak yet" is maybe because he knows that you will.
This is because you can't really tell people (and babies) 'not' to do somehting, because they just 'will do' it.
So, why would he want you to take peak?
Well, maybe it's so you can sort of 'leak' out what you have in immediate memory.
Therefore, when you do eventually go 'over the wall' you'll have gotten rid of all of what you expect to see (from when Win says 'don't peak') and what you actually see will be much more of what your inner mind wants you to see, rather than what you 'think' you ought to see.
Anyway, I hope you followed that lol.
That's just my theory.It may be total rubbish, but it kinda makes sense to me 
I'm sure AlexK will be along soon to clear this up 
Thanks!
