It sounds like you are supposed to make some sort of knot stitch which is to be counted as one st throughout your pattern. The knot st would be performed in several steps but they were all to be counted as one thing when completed. But, as you point out this is an increase they seem to be giving you here and not a knot. Knitting into the front, back, front of the next stitch will make 1 st into 3 sts thereby increasing 2, but producing no knot. Did you quote the directions for the knot correctly? If so, I surely don't understand what they are doing here either.
