Before you re-attach the fan shroud put it in the hole that the nozzle will stick through - from above. Once the nozzle is sticking through the hole it should be held in by the nozzle block.
It's never happened to me but sometimes a part comes loose during a print and although usually it's knocked over, sometimes it is stuck to the nozzle and carried around on the bed. If in addition to these 2 bad things happening you ignore the print for an hour, you will get a massive glob of liquid filament and some of that can get up through into the head and clog everything up. This tiny ring prevents this. But again - 3 things have to go wrong for this to happen so it's a bit rare.
