If a pattern tells you to make [shell in middle of shell from previous round, ch 3, dc in next loop, ch 3, skip dc, ch 3, skip dc, ch 3, shell in midd

If a pattern tells you to make [shell in middle of shell from previous round, ch 3, dc in next loop, ch 3, skip dc, ch 3, skip dc, ch 3, shell in middle of shell from previous round]. How do you ch 3 skip the dc then ch 3 again? wouldn't that be like 6 chains if you skip the dc after the first ch 3?
