That seems inaccurate from the perspective of both physical reality and game mechanics.
Ragged amputation like removing a limb in combat should initiate massive blood loss, requiring immediate treatment to avoid bleeding out. This can, IIRC, be supported with current rules; actually, there is probably no more appropriate situation in which to apply those rules.
Moving on to secondary effects, if bleeding is stopped in time, the now three limbed amputee has to survive the remainder of fight in very rough shape.
After that, we can start worrying about infection.

I contend that there are plenty of avenues for an attack to the arm that severed the limb to cause death without any previous injury whatsoever.
