Confusing instructions

My instructions say, “((k1, yo) 3 times, k1) all in same st making 7 sts in one”

Does this mean k1 and wrap the yarn 3 times after the first K?

Welcome to KH. Here’s a video showing k1, yo, k1 in the same stitch. https://www.youtube.com/watch?v=9h1hfKTsjbM

You’ll k1, yo, k1, yo, k1, yo, k1 all in the same stitch. HTH

You repeat the k1,yo three times in the same st and then add one sc to the same st, so as Grumpy Grandma says… k1, yo, k1, yo, k1, yo, k1 all in the same st. Makes like a fan look, or shell.
