Shaping men's cable armhole

Pattern reads: to shape armholes: keeping in continuity of pattern, cast off 3 sts. Beginning next 2 rows. (these are a K and P respectively)
3rd row: K2. k2tog. Work to last 4 sts. (K2tog. T.b.l). K2. This puts the decreases 2 sts. From armhole edge.
THIS WHERE I RUN INTO A PROBLEM AS TO HOW TO PROCEED:
4th row: P3. Work to last 3 sts. P3.
5th row: K2. Work to last 3 sts. K3.
6th row: P3. Work to last 3 sts. P3.
Repeat 3rd to 6th rows inclusive to 94 sts. Ending with 4th row, then repeat 3rd and 4th rows to 82 sts.ending with 4th row.

Do I repeat as if 4,5,6 were 1,2,3 till I reach 94sts. And then 3,and 4 as if 3 and 2 till I reach 82 sts.?

Repeat [I]3[/I], 4,5,6 until 94sts and then 3, 4 until 82sts
