Because backfill donot have wide rest (heal).

Imbalance of the i.e weak in bearing capacity do cause overturning, backfill should be given precisely so as to be effective.

We can not decide the overturning moment here so it should be improper drainage.

How can you tell that it is only due to overturning?
In the given figure there are weep wholes so there is a defect in a vertical stem so this may be due to unfit conditions of backfill.

The CG of backfill will be just above the CG of retaining wall which tends to overturn it in an anticlockwise direction.

Lack of backfill filter media can cause more pressure. Boulder backing is also an important criterion in case of mass concrete sections. Since this is a gravity wall. Due to the heavy earth behind and high backfill height, Overturning can be considered.
