Nope, that was just pilot bragging. I was a USAF F-4 "guy in back," (GIB) in the early '70s. I once flew a post-maintenance test flight in a clean (no external stores or even pylons) F-4E, at Nellis AFB. Max power (full afterburners) at 40,000' altitude got us to ~1,525 MPH (Mach 2.2) in level flight. At sea level, top speed was around Mach 1.4.
There were proposals to re-engine the Phantom with new turbofans, but it never happened. Instead, the AF bought F-15s (Mach 2.6).
Yeah, it's the little things that count. We used to strike fear in the heart of the enemy by doing low passes at 0.151 mach. Sea-level, of course.
