"Or"??? Which is specified in your draft?

The original request "http://example.com/filename" will cause
SRV look up of "_http._tcp.example.com" and port numbers
and targets are obtained.

As RFC2782 says:

    Priority
         The priority of this target host.  A client MUST attempt to
         contact the target host with the lowest-numbered priority
	it can reach;

"target host"s are "contacted", which means no recursive SRV
look up will occur.

SRV is for hostname in URL just as MX is for domain name
in e-mail address.
