It was an ad campaign Toyota ran in the early 1990s for their Corollas of the time highlighting their twin cam 16 valve engines. They had a badge on the guard from memory, with an emblem showing four valves pointing upwards at an angle, resembling four trumpets being played. Slick marketing, even though the technology existed for decades, but was only beginning to become more and more standard in normal passenger cars.
Back to the little Laser/Meteor, sometimes it takes ages to idle down and I lose patience. Doesn't seem to harm it. It glides rather than bangs into gear thankfully.
I have to mention that I have muddled with the idle adjustment screw and air mixture screw in the past to try and make a difference, to little avail. That might not have been a good idea after viewing those excerpts you posted.
