The problem with cutting next to the 2by 4 is that the dust ends up all over the comb. I try to find the nails and use them as a guide to tell me where the center of the frame board is. In the case of plywood, usually floor boards, we pull the nails out with a cats claw and cut down the center of the 2 by.

In the case of plywood, I follow your lead. To much cutting and time killing with a multi cutting tool. I also pull the nails with a cat claw and usually use toe kick saw or skill saw, for cutting this.
Sheetrock is another matter. This is why I use the multi tool. No rotating blade slinging sheetrock dust all over the comb, no ripping up and down motion creating dust as with a jig saw or hand sheetrock saw, or any other means that I have tried, including razor knife. When you make the top and bottom cut with other means, the globs of dust will fall to the comb any way using other means, that is of course unless you always make your horizontal cuts across the top plate and same way with the bottom plate, taking out the entire hight of the sheetrock, floor to ceiling. The blade simply vibrates at a minimum distance, will not easily cut your hand, (ask me how I know. ;) with a simple un-pressured touch, as compared to any other means, making it not only effective, efficient, and (as close) to dust free, as any way I have tried, but safe to use as well. This equipment operates kind of like barber shears as related to the vibrating back and forth motion of the blade. And one other problem that I have ran into is all sheetrock is not nailed, but in my area the newer homes are now using glue along with a minimum amount of nails fastening the sheetrock to the 2-bys. Love my multi-cutting tools. :)
