To me this looks like it should be two separate lines:
K2 tog twice at start of next 2 rows
bind off 3 at start of next 2 rows.
Which would have you decreasing on the next 2 rows then binding off on the 2 rows following. I don't know.
I would not do my decreases in the first stitch, I would do them one or two stitches in from the edge.
