It matters to Morales. He hasn't fought below 140 in his last 3 fights. He does not need an additional disadvantage to what he already has.
I think this fight may be at JMM's terms since Morales should be the one desperate for this fight. Even at 140, I think Marquez wins this one so why not go for the higher weight to test himself and bring himself closer to a fight with Manny. If this fight is at 135, then it appears that he has relinguish his desire for that third fight.
