I looked at that same screw the first time I did the oil change too, the factory service manual doesn't say anything about it during oil filter change at all even though it is shown in the pics. I was wondering if maybe it was put in by the engineers or something as a possibility to install another sensor or something later on in development..... who knows but no you don't need to bleed anything, just make sure your oil level is up to but not over the max marks in the oil level window while ATV is level and then recheck oil level after you run it for a few minutes.
