The directions seem alright. I think you're reading more into it.... If you are supposed to sl, k1, pass slipped st over, that's what it would say or SKP. Do just what it says: K5, *Sl1, k4, p1, k9.... there is so "psso" and it should tell you to repeat from the * around, which means you only do the K5 at the beginning.
On the next row: P4, *K1, p4, k1, p9. Again, repeat from the * around and only do the P4 at the beginning.
Hope this helps!
