virtual server php configuration

when i create a virtual server, then log in as its administrator…i note the following in webmin>others>php configuration

/home/virtualserver/etc/php7.0/php.ini PHP 7.0 configuration for /home/virtualserver/etc/php7.1/php.ini PHP 7.1 configuration for /home/virtualserver/etc/php7.2/php.ini PHP 7.2 configuration for /etc/php/7.0/cgi/php.ini PHP 7.0 /etc/php/7.1/cgi/php.ini PHP 7.1 /etc/php/7.2/cgi/php.ini PHP 7.2

i am concerned that the “second” part of the above (eg “/etc/php/7.0/cgi/…”) is not contained to just the client’s virtual server, but is a global directory area.

Can someone confirm that i should not be concerned? (which /etc/ directory is this?)
