I think what you're asking about are poses where the root node is saved vs. not saved. If the root node is saved, the character will zoom off to another location, depending on where it was saved and where it is now. If the model is at 0,0,0 and the pose was saved at 0,0,0 then it's OK. With the root node not saved, the model will stay in the same location you have it and assume that pose. There can be issues where the model stays in that location, but the angle is wrong, so you may still have to correct it manually. Understanding the difference should help.
