What does the squat work exactly?

[Joe1234]

So, the dumbbell squat in the gluteus maximus exercise category https://exrx.net/WeightExercises/GluteusMaximus/DBSquat says the target is Gluteus Maximus and Quads is a synergist, but in the quads category https://exrx.net/WeightExercises/Quadriceps/DBSquat the exact same exercise is shown to have Quads as the target and Gluteus Maximus as synergist, so which one of the two is it??? The exercise shown is the same, even the gif is the same gif on both pages
