Hey there,
Well, I would not put too much stock in what you read in the Shaolin encyclopedia.
The currently 'popular' versions of ShaoHuo Gun are not the forms you perhaps think they are.
ShaoHuo Gun is generally said to be named in reverence of JinNaLuo rather than being the style created by him. His weapon is a shaohuogun, a Fire stoking staff as opposed to a regular staff.
Jin Na Luo is a 'JingGang YeCha' 金刚 夜叉, that is if you like the classification of deity that he is. So his style should be the YeCha Gun I think. But as discussed in the other thread, the YeCha Gun is mainly spear technique so may not be wholly representative of the current generation of Shaolin staff.
