You know, oh lead one, that you can bold anything you want, you can scream and yell that I left out context, but the fact doesn't change that the court of review, a post-FISA court of review, found that the President's ability to conduct warrantless wiretaps for purposes of acquiring foreign intelligence from non-US persons is inherent. The part you claim I left out asked if FISA expanded (i.e., made even bigger) the President's inherent (i.e., not subject to regulation by Congress) ability. Not only that, the court found that it did! The case against wiretaps becomes weaker, not stronger, by inclusion of the language you claim I left out intentionally.
What Gonzalez is talking about is that the authorization of force makes US-based agents of al Qaeda to be non-US persons under the statute. That is, the President's inherent power only applies to foreign powers and the agents of foreign powers; declaring al Qaeda to be such a power is what makes it clear that the taps of the US-based agents of it are allowable under the President's inherent abilities instead of under the expanded abilities written into FISA. Other non-national threats to US security (a violent drug cartel, for example) would not be a foreign power and thus the President might arguably not be able to order warrantless wiretaps of US-based agents of such threats. I believe that a FISA warrant would be required to tap the calls of US-based members or agents of Hamas, for example.
