That part you wrote in blue is unclear, but from what it says here: "knitting into the same stitch at the tip of the ear flap, four times" that you would do the i-cord edge to the very tip end stitch of the earflap and work the i-cord thing 4 times into that tip stitch. I don't get the previous rep part.
What you are doing here reminds me of going around corners in crochet, you work extra stitches into the corner. They say 4. That may be needed, but I'd watch how it goes and if 3 seems to do the trick I would do 3 instead.
