Because you have not put all the potential servers into the same definition.
Apache regards one VirtualHost as being different from another.
I mean, suppose you have two VirtualHosts:
music.example.com --> 198.51.100.36
images.example.com --> 203.0.113.78
If you send a request into Apache for images.example.com and 203.0.113.78 is
not available, you're not going to want the other machine which contains music
to try to answer the request, are you?
If you want more than one back-end server to be able to answer a request which
comes in, they must be put into a single VirtualHost definition using
https://httpd.apache.org/docs/2.4/mod/mod_proxy_balancer.html
