Look at the routing table on your nginx server.
If it connects *to* 127.0.0.1, it will connect *from* 127.0.0.1 (which
is one of the nginx server's addresses).
If it connects *to* 192.168.0.1, it will connect *from* 192.168.0.1
(which is one of the nginx server's addresses).
(Probably, if it connects *to* 192.168.0.2 (which is on a different
machine), it will connect *from* 192.168.0.1.)

No, it is the address that the connection to varnish comes *from*. Because
of your specific setup, that happens to match the address that nginx
connects to. But try connecting to varnish from some other machine and
you'll see the difference.

It's usually considered a feature that the source address of a connection
is logged. There is nothing nginx can do to hide its source address.
What you want is something non-standard. Possibly there's a varnish
configuration to allow it.
