Assuming you're using the chore chart with others, you are now assigned the chore twice rather than once in the rotation of the chore. It's no more than a weak disincentive for missing chores. (A better disincentive would be fines as I write about here https://keyankousha.com/the-best-chore-chart-in-the-world.ht... ... which I haven't implemented because I didn't need them in my housing situation as the weak disincentive of more chores worked fine.)
