Marnie, do you mean that if you worked it in the previous row or two, you're not supposed to work it right above it on this row? Ahh yes, I think I get you now. I think you have the correct answer!
I tried doing that once, using that increase along the edge of a small project (I was making a knit heart, from the bottom up), and it gave a very tight edge along the side of the heart. I did the increase every other row, so it didn't ripple, but it was definitely tight and pulled in, and I determined not to use that increase again in that way!
Frank, FYI, two more samples of this kind of increase are KLL and KRL on this site's increases page. Their biggest advantage, that I know of, is that you can do the two side by side, for a double increase, that won't create a hole in the knitting.
