Difference between 'Uses per Coupon' and 'Uses per Customer' in coupon definitions

Can anyone please tell me the exact difference between 'Uses per Coupon' and 'Uses per Customer' fields when defining a coupon?
TIA

Uses per Coupon in the number of times the Discount Coupon can be used in total by anyone ...

Uses per Customer is the number of times a Customer may use the same Discount Coupon ...

Thank you!
