Whoever wrote this didn't pass freshman physics. You may assume that g is a constant for all intents and purposes over the trajectory of any ballistic projectile shot at the earth's surface and travelling several thousand yards or less before impact.
Yeah no kidding. Sure the ballistic arc looks different at an angle but that is not due to gravity changing.
I saw that, too. I sure wouldn’t want Mr. Johnson tutoring my kid in physics. What a dumb thing to say.
Following his logic, gravity has a larger affect on me when walking horizontally than when jumping vertically. Gravity “knows” which way you are moving.

Agreed. The writer should stay away from physics, unless they want to use vectors correctly.
the author, and many, are making the math mistake of assuming that distance over which the gravity is applied is measured by line of sight, not in the horizontal. This is a practical way of measuring distance in the case of shooting up/down a slope, but you have to compensate for the difference in the line of sight distance to the horizontal distance (some simple trig). So yes, this is someone who is trying to impress you with what he knows but cant apply properly the physics he wants to so impress you with.
