This is irrelevant. The exercise was dogfighting, a phase which the F-16 would never be able to reach against an F-35 in combat without a multitude of things going wrong.

The F-35 can see and shoot down the F-16 with radar-guided missiles in BVR well before the latter is even aware the F-35 is in the area.

Dogfighting is minimally relevant to modern air combat for nuclear-armed nations. Things would have to be going extraordinarily badly in a war for the brass to start deciding to send their exceedingly expensive fifth-gen stealth fighters into dogfight coin tosses.

Hell, even an A-10 is a surprisingly effective dogfighter against modern fighters. The fighters have speed but the Warthog has an extremely tight turning radius and far better low-speed maneuverability, both of which allow it to stay inside the opponent’s “bubble” (the area inside which a turning jet can’t ever manage to point its nose). If the A-10 can keep it to a one-circle fight it will win handily. A fighter will often have to rely on a “boom and zoom” tactic (where it disengages, gains distance, and turns back around for a guns pass) but that can be quite low probability of kill and still be relatively risky if the A-10 has friendlies in the area feeling it location information.

But just like the situation already being discussed, this is for all practical purposes completely irrelevant. A flight of F-16s would engage and destroy a flight of A-10s from miles away with AMRAAMs and it would never have a chance to transition to an up-close dogfight.
