I am not a US citizen but doesn’t this “second time” refer to some kind of promise the NSA made not to spy on US citizen?
For me and the vast majority of the world population the distinction doesn't matter, because according to US law the NSA is allowed to spy on us as they please. Of course, this practice is illegal were we live, but that's not going to bother them.
I think you are moving the goalposts with terms like “looking into”. They are in possession of it and have permanent access to it. For emails and SMS, this involves full content, too.
It even includes US-US communication if the stored communications provider replicates it out of the country, which is so common as to be expected in almost all cases.
