Yes, 'cont in this way' means work in the stitch pattern you've been doing. You must have done a dec row before and you do it again on the next row, then the 6th row after that. There's 5 rows with no decreases between them. Then you work the decrease row on the 4th row 3 times (3 rows between the dec rows), then on every other row until you get to the right number of stitches.
