There is always a combination of energy pathways metabolizing various energy "substrates" at varying rates. The intensity of exercise, dictates to some extent the proportions or the "rate of metabolism" of some of these energy substrates.
Typically, people who casually toss around terms relating to metabolic processes seldom understand the "big picture" and tend to incorrectly give inappropriate attention to a single process regarding some given energy source being utilized at some given intensity.
Much like your remarks.
