Misprint?

Does anyone have a suggestion for these directions? They read change to size 7 needles and yarn A and beg with a P row work in reversed st st, working 12 row stripe.
rep as folls:
4 rows B, 2 rows A, 2 rows B, 4 rows A…my question is why did they have me change to A and they say the pattern starts with B? Should I start at the other end and do 4 rows A first?

I think you’re right, its a misprint:-x . Dont change to A, just start with B.
Does that match the picture on the pattern?

It’s not a critical pattern, it’s called a herringbone stitch, with tweedy yarn so doesn’t show mistakes easily. Thank you.
