He can be hot or cold, but he will always chase, and extremely doubtful that will ever change, it typically doesn't for players, the aggression is built into their personality, like Javy. It is what it is, we have to accept it.
Any pitcher who can locate their fastball high out of the zone or breaking stuff low out of the zone is going to get PCA out. For some reason they kept coming inside on him early in the season and he was launching them, maybe they stopped locating there in the 2nd half, not sure.
