Not 100% accurate. Read about HTTP/2 & HTTP/3 Connection Coalescing https://blog.cloudflare.com/connection-coalescing-experiments/TL;DR Domain Sharding used to be an optimization technology primarily for HTTP/1 - use with care on HTTP/2 (in many cases don't do that at all)

Example of it in action on my Wordpress blog at https://blog.centminmod.com/ for HTTP/2 dependency chart and connection waterfall where 3 of my subdomains serving assets are utilising connection coalescing

Though it still matters the order/prioritization of assets even on sharded domains.
