Sort of: it doesn't differentiate between DoH and normal resolution (it only does IPv4 TCP & UDP resolution). This means that it will return Cloudflare (i.e. ASN of CLOUDFLARENET), but probably the same Cloudflare as if you are using Cloudflare's public DNS servers.
Tip: You can check a specific DNS server with dig and curl:
UUID=$(uuidgen)
dig ${UUID}.which.nameserve.rs @1.1.1.1
curl --silent https://which.nameserve.rs/debug.txt | grep ${UUID}
and then do a ASN lookup on the IP address
Note: the debug page is unofficial, and may change, so don't bake this into anything.
