Copied Offers

[Matthew Flaschen]

I found another FAQ Entry 
(http://www.gnu.org/licenses/gpl-faq.html#RedistributedBinariesGetSource) 
that says:

"My friend got a GPL-covered binary with an offer to supply source, and 
made a copy for me. Can I use the offer myself to obtain the source?
     Yes, you can. The offer must be open to everyone who has a copy of 
the binary that it accompanies. This is why the GPL says your friend 
must give you a copy of the offer along with a copy of the binary---so 
you can take advantage of it."

According to this interpretation, any copy of the offer is valid with 
any copy of the binary.

This answer supports my argument, except for its claim that the offer is 
only valid for those who have a binary.  I don't see how this 
requirement is stated in the GPL.
