To be honest I think it could. It sounds like diaper dependency, you're getting more comfortable wearing and using your diapers. Just be careful. Keep an eye out, if you spot it happening more and frequently you'll need to take action. I don't think it'll be that fast but just keep your eye out. Maybe wear pull-ups during the day if you're worried about an accident and it'll be safe. If you find you never have an accident like that then you could go back to underwear. Or maybe a guard or shield in your underwear if you're nervous.
