Again the photos leave a lot to be desired but in the second photo there seems to be a bevel just inward of the stitches...as if a shallow channel had been cut. Even if the leather is terribly flanky and loose fibered I doubt tightening the stitches could produce that effect by itself. Stitching aloft means stitching on the surface.
And as an aside, anytime the shoe is seamed directly to the insole, there is a holdfast whether it is stitched aloft or not, whether there is a "feather" or outside channel or not. We would all like to see a definitive, structured holdfast (or at least I would) but all a holdfast is, is the substance (in this case, of insole leather) between the two sides of the inseam. It "holds" the stitches "fast" (another word for securely). It may be worth remembering that even gemming is a "holdfast"...technically.
PS...and on edit...I might add that inseaming from the outside-in is strange, to say the least, and fraught with potential problems. Additionally, the stitches here are half again to twice as long as I would consider "best practices."
