Help understanding pattern

I am working on the right front of my sweater. I BO the first 24sts for the neckband but am confused about the next part. Do I dec like this?
row 1 BO
row 2 P
row 3 K
row 4 P
row 5 dec
row 6 P
row 7 K
row 8 P
row 9 K
row 19 dec
One time on 4th row and the next time on the 5th row. Then on the 4th and 5th again?

Neckband: When the piece measures 30-32-34-36-38 cm bind off 24 sts at center front edge for neck. Then dec 1 st for the neck on alternately every 4th and 5th row a total of 13 times.
Armhole: At the same time when the piece measures 34-35-36-37-38 cm bind off for armhole at the side as on back.
After all armhole and neck shaping is complete 5 sts remain on each shoulder. Bind off when the piece measures 54-56-58-60-62 cm

Yep–sounds right to me!
