It is possible that not all employees at Larian are allowed to change everything or add Osiris code.
So adding completely overpowered stats and applying them to players might allow them to test things which cannot be tested with a level 1 player. And one can not play through level 20 just to test a little thing.
So I'm pretty sure that entry is used for players when testing stuff.
There are some other stats that seem to be unused like "Henchman_Alfred_Fighter" and "Henchman_Frank_Archer". They can give some hints about the history of the game's development ;-)
You can find more unused stuff, most likely left over from testing. Just look at all the "Cheat..." entries at the bottom of TreasureTable.txt.
