Bush isn't going to stop doing what is necessary...he is just pacifying the baby politicians that have their feelings hurt.
By doing THAT, he IS doing his constitutionally mandated job...keeping our country safe.
To hell with the Congress and their lust for power and attention.
You're exactly right and this "agreement" gives the President the option to have FISA review it. He'll probably send FISA a couple of border line test cases to see how they're leaning on that day and then if it looks favorable he'll let them see the whole program.
