It's not *that* weird for a DH bike from when these molds were created. Maybe a bit on the short side for a large, but this is pretty "normal" for like, a 2016 DH bike - recall these had been around for a number of years as the Evolve Sky Pilot, and geo is offset a few years on open mold chinese bikes.
Part of the issue is because of the super slack head angles combined with long axle-to-crown length forks, seat angles, and long wheel bases, reach is no longer the helpful size summary we treat it as on trail bikes. You're much better looking at numbers like effective top tube, wheelbase, and rear centre to figure out how a DH bike might fit/ride on paper. That said, the thing is still small when you look at those numbers.
For example, the Norco Aurum HSP which was fairly cutting edge when it was released in 2019 sported a 465/473mm reach in its largest size (dubbed an L/XL). Recently, DH bikes have gotten much longer - but this trend has only occurred with the current resurgence of DH investment and tech.
So this is probably "fine" for someone looking for a decently competent DH Bike to this day, but probably only for someone up to 5' 9" or so. Consider their sizing as 'small' and 'medium' now, rather than medium and large.
