We don't know that Madregot runs ONLY from Yesod to Briah. And I think
there are implications that being at the brook(s) means you are outside
space and time, hence outside all universes.

Anyway, as I understand BotNS's time scenario, an event in the past can 
lead to multiple branched futures. Thus a linear time traveller would perceive
one brook travelling backward in time but multiple brooks travelling forward. 
This allows Madregot to be both singular and plural.

A superior time traveller would be able to go sideways and diagonally and 
able to traverse all possible pasts and futures. To use Wolfe's chessboard 
analogy, normal humans would be pawns able only to move forward in time 
in small increments. Master Ash, the Green Man, sometimes Severian and 
probably Juturna are rooks. Tzadkiel is a queen.
