I don't understand the question at all. You want to know why someone who considers himself a chossid brings in his Rebbi?
For starters, I didn’t read the Hebrew until
@imayid2 pointed out it's a botched translation. I didn't understand why the Yanuka was being labeled as a chossid of the Rebbe. Now that I read the Hebrew, it makes a little more sense. I still don't understand the public proclamations of "allegiance" to a new Rebbe, nor the comparisons to the Lubavitcher Rebbe, but to each his own...
