Hello,
I am making a sweater and am about to decrease for the arm holes for the second time! The pattern says to bind off three sts at the beginning of the next two rows. I did it the first time just as the pattern states but it didn't like right. It looked as though one side was lower than the other. So when I knit the eight more inches I need for the armhole one side would be a slight bit longer than the other. Why wouldn't you decrease three stitches at each end of the same row? Hope someone can clear this up for me or am I just over thinking this! Thanks Midge

Yes, they're on different rows, but when you BO for the shoulders, the one you bound off first for the underarm will also be bound off first for the shoulders. So the armholes themselves will have the same number of rows to them and the 1/6" difference really isn't noticeable when you're done. And you can't BO at the end of a row and keep knitting; the working yarn would be at the edge and you'd have to cut it to work on the sts.
