Mike,
I don't know if that really explains SWR, but with the different loads,
I "get" what you are alluding to.
One comment is that those feedline lengths should be electrical lengths
- they will be shorter than the physical length by the amount
contributed by the feedline velocity factor.
After (or before) that experiment, grab most any good book on antennas
and transmission lines, looking with particular interest at the sections
dealing with mismatched lines which are directly associated with SWR.

If you truly want to understand SWR, I recommend you pick a frequency and
make up a 1/4, 1/2 and 1 wavelength sections of 50ohm coax.
Then measure the SWR at those points into various different resistive
loads, like 10, 25, 50, 75, 100, 150 and 200 ohms.
I think you will find the results very interesting.
