In this interview, he speaks with modesty , no unnecessary mocking.

this person really has two personalities

Wemba didn’t become a hero National because of the ngulu-affaire (it made btw the press of Congo  and bandleaders ridiculize him and kill his image for politicians). They made Wemba a Hero National for the way brought Congolese music on another dimension and make it known in countries like Japan and for the new he influenced a whole generatiosn with La Sape.
