What does "end with a ribbing row" mean?

I’m doing a simple scarf - my first! Never read a pattern before. The instructions are:

  • Purl 2, knit 2, repeat from * to last 2 stitches, purl 2.
    Repeat last 2 rows until ribbing section measures 10" ending with a ribbing row 2.

OK, I know this is a simple ribbing pattern 2 and 2. But what does that last line “ending with a ribbing row 2” mean?

Thanks!

There seems to be a row 1 which you didn’t put in which is alternated with row 2. When you’ve reached 10" and have finished row 2, go on to the next part of the pattern.

OK, that makes sense now. Yes, it’s the 2nd row of the ribbing. Thanks! I love this site!
