Do they really solder the steerer to the fork crown?
Never knew that about changing the thickness of the tubes.

'Soldering' isn't technically correct - it will be brazing or silver soldering, both of which use more heat (oxy acetalene) than what a plumber may do and either brass or silver filler. Its nearly as strong as a weld but involves less heat and distortion.

Re the wall thicknesses - find a good steel frame and ting the tubes with your nail, they will be higher pitched tings in the centre of the tube due to the reduced wall thickness - all part of the magic of steel frames

Nice little animation here showing how butted tubes are made.

People get a bit carried away imho - you can clear it up with some over-the-counter cream.
