http://www.pool.ntp.org/ redirects me to https://www.ntppool.org/en/.
http://pool.ntp.org/ takes me to an "It works!" default Apache 2 page for an Ubuntu installation. As the comment in the issue describes, http://pool.ntp.org/ takes you to a random ntp server.
If you want another example, try google.com using Google's own DNS:
PS U:\> nslookup - 8.8.8.8
Default Server: google-public-dns-a.google.com
Address: 8.8.8.8
> google.com
Server: google-public-dns-a.google.com
Address: 8.8.8.8
Non-authoritative answer:
Name: google.com

172.217.8.206
> www.google.com
Server: google-public-dns-a.google.com

Even if you ultimately end up at the same site through redirects, you're clearly not going to the same site initially.
