My problem with "primary" and "secondary" (as well as the old terms) is 
the daisy chain scenario.

I have started to use "leader" and "follower" in many cases.

A is the 1st leader

B is the 1st follower and 2nd leader

C is the 2nd follower and 3rd leader

D is the 3rd follower

I suppose you could also use "upstream" and "downstream"

A is upstream of B

B is downstream of A and B is also upstream of C

C is downstream of B and C is also upstream of D

D is downstream of C

"leader" / "follower" and "upstream" / "downstream" are relative names 
while "primary" / "secondary" sort of imply ultimate position with 
"tertiary" etc coming into play.
