Seemingly. When Intel makes a line of processors, it markets that line in multiple speeds. As the processors come off the line, a certain number (determined by marketing) are tested at the highest marketed speed. Those that pass are boxed and sold at that speed. Those that don't go back to the bin. Most that function pass. Then Intel tests a certain number (again determined by marketing) at the next lower speed and so on. They do this to maximize their profits from one line. This means that even the lowest speed processor off the line was designed for and probably would (not guaranteed) operate at the highest speed for which the line was designed. This led to the not too uncommon practice of "overclocking" lower rated CPU's. Intel now alters it's processors post testing so that they will only operate up to the packaged speed.
Asahi did not guarantee the accuracy of the unmarked speed, but unlike Intel, they did not prevent you from selecting it. It's about getting as much out of the market as you can with minimum change in tooling.
