As I mentioned a few times on this forum, it is not known so no matter how much you try to understand, you will not. It is based on experience and neurophysiological basics - XII cranial nerve is hidden and short, thus it basically cannot be damaged along its course like e.g. nerves going to calves. Also bulbar area is rarely affected in benign disorders generally and this all together gives this infamous opinion.
However, it just common opinion and nobody really knows. Look, it is not even known why and where exactly fasciculations are generated! So do not expect that there is a doctor that could answer this question.
I went through this phase 3 years ago...
