I have that book, and it's partner for cuff down socks, and I certainly didn't pay anything like that!
I don't think the instructions are wrong - unless I have a dfferent edition to you. The only date in mine says copyright 2010.
You have been knitting the foot in the round.
Then work the instep stitches (knitting in the same direction assumed)
Rearrange the distribution of the stitches, but don't turn the work, it doesn't tell you to.
Then the first row of the heel is still going in the same direction, it is to knit 32 sts then turn.
Next row is purl.
After that it's alternate knit and purl rows until the heel is complete, ending with a knit row. No instruction to turn.
Redistribute the stitches and continue knitting in the round.
