Given, N _ _ J
Let's say the sequence is
N, M, K, J
You're correct: there are three people after N.
But there are only TWO people who are both after N and before J.
The rule is alluding to, in this case, M and K.
Looking at N, M, K, J,
we could say "there is one person before K and after N" (we'd be talking about M)
You're hearing this as
"there is one person before K and there is one person after N"
But you need to hear it as
"there is one person who has this trait -- before K, after N"
The rule for N _ _ J is saying
"There are two people who have this trait --- after N, before J"
Hope this helps.
