hexagon socks..need help

[yarn mechanic]

hey ladies..i am working the "Star Treatment" hexagon sock pattern in the latest "Knitter's" mag...i can't find help through their site, but the question is this: if you have 6 stitches per circular needle, 3 needles, and you decrease like this: (k2tog, k1), will you ever end up with 2 stitches per needle? i have done the decreases and i have drawn it out and i just don't get it? i can't end up with 2 stitches per needle, as the pattern suggests? any help is appreciated...
