At a guess -- there does not need to be exactly one resolver directive;
and there is no need to avoid the system resolver at startup because
things are under less time pressure then.
The "resolver" directive takes the address of a DNS server. The system
resolver may or may not use DNS -- applications don't have to care what
it uses, just that it works.

You can use the same DNS server that the system resolver uses,
yes. (Assuming your system resolver uses a DNS server.) But you won't
be using "the system resolver".
The difference there may not be important.
Good luck with it,
