I am not sure how mysterious this is. As Scott Gottlieb (hardly a COVID denialist) pointed out[1], we are getting the impacts of some level of immunity in populations. Herd immunity itself is a threshold, but it isn't a binary state. As you near it, the "susceptible" pool becomes fewer and fewer. Since reinfections appear rare (though not impossible) and immunity seems robust and at least 6-12 months long, it is no mystery that cases will begin to fall.
