I have to respectfully disagree. A short field landing is where you
plonk the airplane on the runway while it still has some flying speed.
If the airplane is slow enough, the landing impact will absorb enough
energy to prevent a bounce back into the air. On a normal landing, it is
quite possible to squeeze out every bit of excess airspeed in the flare.
When the airplane starts to descend despite the pilot's attempts is what
we normally consider as the onset of stall. Perhaps the word 'fall' is a
bit too strong for this situation because you are not falling more than
a few inches. If you are only inches above the runway, the vertical
speed will be virtually zero, and the touchdown should be smooth.
However, it is quite possible to land an airplane in flying speed as you
described as long as it is not too fast. I believe in this case you are
using the energy dissipation due to the touchdown to prevent the
airplane from bouncing back.

Every landing involves a stall.


No, not every landing does. In fact, preferably few do.

But that is not the same as a stall during
flight because you don't fall more than a few inches.


IMHO, it is generally poor technique to "fall" at all during a
landing. One exception is a short field landing where minimum
airspeed is the highest priority, even if it means a "firm" landing.
There may be other exceptions, but otherwise the landing should be a
smooth, controlled descent with the airplane still flying when the
tires touch the pavement and vertical speed as close to zero as
possible.
