Actually, I would call it a Semi cascade:
"This is not a precise rule and much depends on the visual mass of the bonsai design – a strongly horizontal mass would still be classified as a semi-cascade even if it came well below the pot rim"
A photo made in line with the pot, horizontally, in stead of from an angle from above, would help to confirm this.
