Yes, it can be. See your own screenshot, where they say reviews are taking longer than normal.
Also, it depends quite a bit on what your app does. I published a version of my app that now contain geofences and oh dear, it took a long time for them to go through all permission texts and video clips and whatnot. I think it took them like four or five days. After that I published a quick update fixing a bad bug, and they let that through in 15 minutes. I guess they have some sort of system where they see that I had just made a small change - and perhaps not even needed human verification from them? Who knows.
