st: Difference between 'at' and 'over' option in margins.

Hello Everyone,
Can someone explain me why do we use the 'at' and the 'over' option
together in the same margins command given that the over options
anyways restricts the sample.
margins, over(sex) at(sex=(0 1)) post
why use the at(sex=(0 1)) when over(sex) already restricts the sample
first to sex=0 and then sex=1
Thanks
Natasha
