Maybe you mis-read my post. What you describe is exactly what I had - a shower head with an on/off button. Despite this, when turned back on it was all hot for a few seconds. So it wasn't that I had to readjust the valves - they were already adjusted. I am just thankful it wasn't my son that got burned.
My shower head with the push button does the same thing. Not sure how the water remains circulating but it's just a straight hot water blast till the tempered water mixes in a few seconds later. Must be a design flaw since we both have had that happen

When you stop/limit flow thru shower head using the on/off button/lever on the handle the shower faucet acts like a mixing chamber.....
Hot water typically is at a higher pressure then the cold water due to pressure increase in WH tank from heating the water (it swells when heated/pressure increases from the swelling)
So when you turn shower head back on...hot water flows first until mixing of hot/cold in faucet catches back up with previous adjustment of knobs.
Simple thermal dynamics .......
Simple 'cure' ---- turn shower head away from you when first turning it back on via shutoff on handle.
Slow learners may require getting hit with that hot water a couple of times but should come to remember to turn head away initially.
I appreciate the explanation about the thermal dynamics makes sense.
To bad the rest of your answer shows you to be an a**h**e
