Because why not?
Since Apple game plans years in advance, my guess is the new 2021 MacBook Pro enclosure was in the works for 3-4 years. And that was before it was delayed from its planned unveiling at WWDC 2021. Apple likely initially designed the new MacBook Pro to accommodate both customer feedback & Intel processors (i.e. Alder Lake). As Apple's custom Mac silicon ambitions evolved, Apple likely kept the overall design just in case their internal transition timetable slipped. It's always good to have backup plans, as Steve used to say.
It's not like this would be unusual. Apple's adjusted thickness between models recently with the iPad & iPhone, for example, to accommodate a bigger battery or mini LEDs. They thinned out the late 2013 retina 13" MacBook Pro from the early 2013 retina 13" MacBook Pro (0.75" to 0.71" thickness). A great example was the leap from the first generation iPad thickness to the iPad 2.
People would prefer a thinner, more svelte MacBook Pro — so long as it still feels rigid, battery life remains excellent & it doesn't thermally throttle! Thinning it out again makes some sense. Apple would probably shave off a few millimeters in thickness as the M2 Pro/Max will be more energy efficient & can implement a smaller battery. The thinner MacBook Pro would be noticeable but not as dramatic as the rumored new MacBook Air.
