Purgator-
Yes it explained, but unfortunately almost entirely incorrectly!!
There is no hard and fast rule as to whether fuel is loaded in front or behind the CG. Most designs put it as near as possible to ON the CG. The aircraft HAS to be able to stay within CG limits throughout the flight, so has to be able to use any fuel on board whilst still being in balance. CG is not an over-riding consideration in terms of fugal jettison or otherwise.
Additionally, conventionally laid out aircraft become more maneuverable as the CG moves AFT, not FORWARD.
Overweight landings do often require maintenance action as for the same VERTICAL acceleration, there is an increase in the amount of KE absorbed by the structure (KE= 1/2Mv^2. Momentum = M*V) HORIZONTAL velocity makes little difference to the strains on the airframe.
