After thinking about it, I realized depth of batting would have nothing to do with the issue. It may be that the demo used binding strips cut on the straight-of-grain while you may have cuts yours (as I cut mine) on the cross-grain. Cross-grain strips have a little more stretch to them than straight-of-grain.
I don't use the tool, but do leave a 1/4" gap--works great for WOF binding, for Length of fabric I usually will do a scant 1/4" and if using bias binding I aim for between 1/4 & 1/2" gap.
