They're not worked the same way and I covered that - after the p1, bring the yarn over the needles to k2. When you go from a knit to a purl you make a regular yo then bring the yarn to the front, sort of 1½ wraps around the needle, not a full 2 wraps. When going from p to knit, you only have to lay the yarn over the top of the needle loosely and that makes a yo that's like half a wrap.
