I think it goes further.
The idea is the nose wheel lands first, deforms, collapses and absorbs energy, then the main wheels, repeating the process, and finally the added protection of the "crumple" of the frame and honeycomb beneath the seats. Of course it is not totally predictable; the wings might impact first if a tree stump happens to be at the end of the wing! Doubtless the dynamics would then be different.
However which ever way it would be surprising if the G loads were greater than the G experienced in basic level aerobatics.
On the other hand should an aircraft land conventionally and impact on the landing roll the G could be significantly higher and doubtless much more likely to compromise the avionics, never mind the occupants.
