Yarn forward question in British pattern

I thought I knew a little bit about knitting, but this pattern has got me :?? .
It’s a pattern for a vest starting with a 1/1 rib and the pattern itself is “1st Row - S1, * yfwd, k2tog, rep from * to last st, k1. 1st row forms patt. Keeping continuity of patt cont without shaping…” It is not a “lacy” pattern and shouldn’t have any holes (in fact from the photo it looks quite compact). I’ve got holes everywhere and I’m not sure how to continue with the 2nd row (which is the wrong side of the piece). Any advice would be great!

A pattern in which the row is yo, k2tog will give you holes–that’s what you do to [I]get[/I] holes.

What are the directions for the wrong-side rows?

Pattern says simply: “Keeping continuity of patt (throughout) cont without shaping until work measures… ending on wrong side”.
However, I thought the left front instructions would give me a little more insight:
"1st row - S1, *yfwd, k2tog, rep from * to last 2 sts, k2.
2nd row - S1, k1, * yfwd, d2tog, rep from * to last st, k1.
1st and 2nd rows form patt. Keeping continuity of patt (throughout) cont until work measures… ending on wrong side."
I just keep thinking this is a type of yfwd that I’ve never met in my knitting travels before ??

Used in this context, the yfwd is the same as a yo. It’s possible that you don’t see the holes in the picture because they’re like the purls in a rib pattern - it would have to be stretched to see them.
