No. In the first step, the batting is on the carpet; batting will stick to the carpet without pinning, much better than fabric will.
Second step is to lay the backing fabric over the batting. Once you have it centered and positioned as you want it, you fold half of the backing fabric back over itself. This keeps it in position, but exposes the batting. (Before spraying, you probably want to place some towels or newspapers around the edges to catch any overspray.)
Spray either the batting that is exposed, or the wrong side of the backing. Fold the backing back and smooth the surface so there are no wrinkles. When you are satisfied with that half of the quilt, fold the remaining half of the backing fabric back over itself, exposing the unsprayed batting, and repeat the spraying and smoothing process (smoothing from the center out).
Once the batting and backing have been spray-basted together, you flip the entire sandwich so the backing is underneath and the other side of the batting is exposed. Layer the top as before, getting it positioned as you want it first, then folding back half of it to prepare for spraying.
