It may mean nothing if writer/source didn't understand it's a legal term of art.
Why do you believe upstream can't be for a selector itself? Like "AAwlaki@Awlaki.net"? @JameelJaffer @charlie_savage @normative

It can be, but according to NSA/PCLOB, they can't scan just the packets not the content
-
I don't read PCLOB as saying that. They specifically talk packet sniffing,
@JameelJaffer@charlie_savage@normative -
And specifically say they can get selector that is in From line.
@JameelJaffer@charlie_savage@normative -
Yeah, but might be hard to distinguish an “original” header from a forward.

Right. Point being one application of upstream to get emails from non-prism providers
@LizaGoitein@JameelJaffer@charlie_savage -
Would be very surprised if they don’t have a way to get “from” targets via PRISM.
-
They can do just to/from using PRISM, but not using Upstream, or so they say.

Can you cite what you mean bc I must be misunderstanding.
