Non-US Packages

[Juan Pablo <jp_listas@yahoo.com>]

It's not clear to me what does Non-US mean?
I read at
http://www.debian.org/mirrors/list-non-US.html and I
conclude it's about software wich is restricted to US
(i.e. prohibited to export but available from other
countries)
But then I found 
http://www.debian.org/mirror/mirrors_full.html and it
says this are " packages that can't be distributed in
the US due to software patents or use of encryption."
So, what's the truth?

Thanks,

Juan Pablo

P.S. Both pages say at the bottom "Last modified: Thu

change, isn't it?
