Possibly, but the way you were doing it was definitely broken.

Huh? There is only one config.status, and it'll update all its output
files whenever it runs. I don't see the issue.

Excess runs of config.status. stamp-h has to be touched after making
config.status, not before. Also, although this may be a third-order
consideration, I direct your attention to configure's --no-create
option...
