Given +trace isn't "simple usage" (dig @server name type), why would
one say that in the simple usage section? +trace states that it is
going to talk to each server in turn.
+[no]trace
Toggle tracing of the delegation path from the root name servers
for the name being looked up. Tracing is disabled by default. When
tracing is enabled, dig makes iterative queries to resolve the name
being looked up. It will follow referrals from the root servers,
showing the answer from each server that was used to resolve the
lookup.
+dnssec is also set when +trace is set to better emulate the
default queries from a nameserver.
