Izy I have the same feature on my machine, but its called the "Fix Stitch"... I looove it!!!
Lately though I have taken to not backstitching but leaving my beginning and ending stitches long so that I can hide the stitches between the layers, so I don't see any extra thickness from the fix stitch. I has a more finished look I find. I have been suggesting that technique for the last couple of my quilt classes too.
