if you check store value, the value is stored with the record so each time you come back to that record its what it was when you left. If you don't store it, then the value doesn't stay with the record. You can either source it and it'll always have that sourced value or you can treat it like a flag and it'll keep its value in the User Event scripts but after that it goes back to whatever the default is since you arne't storing it. (Basic idea)
