retaining walls are generally retaining earth / ground. It would be
impossible from those concrete clad reinforced earth ramps in the video to
deduct whether the concrete is just a cladding or is actually a retaining
wall or is a cladding for a retaining wall made of concrete (for example).

for a retaining wall, it does not matter why it was built, it matters how
it works.
