TFL/Hip flexors activation

[Mohammed]

Hi there awesome people of this planet,

I want to use the bodyweight sissy squat with no tensor fasciae latae involvement.
https://exrx.net/WeightExercises/Quadri ... SissySquat. Its done with shoulders behind hips and there is no TFL/hip flexors mentioned.
But here
https://exrx.net/WeightExercises/Quadri ... ssySquatAp
They're mentioned WHEN shoulders are behind hips.

Is there an error?
Thank you!
