Your reasoning seems incorrect, but I no longer object to your conclusion.
(If someone claims that the Latin alphabet has upper and lower case
then you could use the same reasoning to deny this and say that
such a distinction is invisible in a single-case-only font.
One has to find a way to distinguish "intrinsic" character properties
from "accidental" glyph properties, and the only way to learn about
intrinsic character properties is to examine the printed texts
in a large representative collection.
I think (based on little evidence) that Urdu writes this double-eyed h
with essentially a single glyph form, and the few cases where I have seen
more than one form, the distribution of forms was not always the same.
My tentative conclusion is that double-eyed h has no systematic shape
variation dependent on position, other than that implied by the presence
of connecting strokes.
I think (based on little evidence) that the Uyghur h is written with
two forms, dependent on position, and the dependence is well-defined
when it occurs.
I stopped objecting because I find that the webpages in Uyghur all use
U+06BE, so this is not a Chinese draft standard, but it is reality
in daily life.)
Now I started asking about Kurdish.
Actual practice seems to be: Kurdish H uses U+0647, Kurdish E uses
U+0647,U+200c or just U+0647 before space. (I still must find examples
with final H.)
