They just playing with the feelings of the opposition, first ask
to update electoral list, boundary changes, etc.
Why not announce all this in one go? Don't tell me he doesn't
have any kind of management skills? 
He makes the opposition wait in eager anticipation for an
election, then puts them off, hoping that when the real election
comes, the opposition members will have lost some spirit, it's a
kind psychological warfare. 
He probably has spies in opposition parties to let him know the
sentiments of the opposition parties. 
Imo, their tactics is to hold up time.
So that they will have less window time to get prepare for
GE.
