All your inferences are based on the limited range of PL-15. So the question is, where did you get the specific range of PL-15?
It's easy to calculate because we can relate it to known figures of other missiles.
AIM-120A/B's NEZ is 20 km, and the Europeans said Meteor has 3 times that, so Meteor is 60 km.
PL-15 exceeds Meteor's range. We know Meteor can do 250 km, so we can estimate PL-15 for a range up to 300 km, both could drop well below mach 2.5 at that point. And we know the Dmax of PL-15E is 145 km, so max range should be 200 km.
Now with just 10-15 seconds of boost, the PL-15 starts losing energy around the 50-55 km mark. If a target is around, the seeker will pick it up and a second pulse is activated, that's about an extra 15 km. So this way the missile is at its highest speed throughout the flight profile until target miss/impact. That's how you get NEZ. Highest speed and highest G performance with highest SSKP during impact against a target that's maneuvering and using countermeasures.
