OK, my re-interpretaion:
a) A some depression (a window), a misshift could occur.
In rel life, this is generally true)
b) but =, you don't create the mis-shift everytime you go though the point
c) The "miss-shift" would occur ONLY IF you stayed in the window area "too long".
In "real life" , the grind would occur if the clutch was not depressed enough after the gear was selected. e.g. The noise would occur after:
Clutch not down all the way
Gear shift moved, but not into position yet
So, it's not necessarily the clutch position, but the "Neutral to gear play" you need to be looking for as well as clutch position (from some depression to rest).
e.g. Not in neutral and not in any gear and clutch between say 30 to 100% depressed.
