Is this seki in the corner

   

I'm not sure if the following is seki in the corner. Could anyone help? Thanks! --amaebi

Is this seki?

Pretend it's black's turn to move first in this position. Does black have a useful move to capture the white stones? Now pretend it's white's turn to move first in this position. Does white have a useful move to capture the black stones? If the answer to both of these questions is "no", then it's a seki.
