Help Needed Reading Pattern

The following set of instructions come from a Tahki Yarns book: Fold-Back Front Cardigan. I’m working the 2nd size listed.
This is part of LEFT FRONT
"Shape Armhole
(RS) At armhole edge, bind off 0(5, 5, 5) sts once, 4 sts 1 (1,1,2) time(s), 3 sts once, 2 sts 1 (0,1,1) time."

Wrong side rows are simply matching the stitches.
The question I have is whether the line above represents 1 row only, or if it represents numerous rows… the first time binding off 5, then a wrong side row, then binding off 4, then a wrong size row, and so on until, for my size, I’ve worked 3 RS rows and 3 wrong size rows … OR whether for my size I simply bind off 5, 4, and 3 all on the same row?
Any help is much appreciated! This is my first wearable project. Reading patterns has been harder than the actual knitting!!! :woohoo:

The instructions are for four RS rows.

First RS row you bind off 0(5, 5, 5) sts, second RS row you bind off 4 sts 1 (1,1,2) time(s), third RS row you bind off 3 sts once, fourth RS 2 sts 1 (0,1,1) time.

This shapes the armhole.

Thanks so much. :muah:
