If monitored over a longer period of time I'd say it is interesting. It also may be good to remember that updates don't immediately cause inactivity. If people are to quit after an update, it might take a delay of x amount of days, weeks, or whatnot. There can also be other reasons for temporary lapses in activity. Right now reduced activity can be due to exams as well, for example. Well it will continue to log, that's no problem. I wasnt refering to quitting, i meant how long it takes for players to come back (as a common counter to the whole "66% of players are bots, look at numbers after update" is that players take breaks/have weekly shower etc). Also dont forget this is global, it may be exams where you are, but not exams in other countries. But that's data mining for you correlation and causation can be mixed up.
