Help with instructions! Please!

Can anyone give more instruction on this next line from the patttern I’m working on?

Dec 1 st 6 times at armhole AT SAME TIME [dec 1 st at neck edge on each of next 4 rows, work one row even] 6 times.

Any help would be greatly appreciated! Thanks so much!

At the same times means that while you’re doing the decs at the armhole edge, you’ll also be working on decs at the neck edge.
