Because he wanted to divert attention from a different, unavoidable, embarrassing revelation.
What revelation is that?
The revelation disclosed here as a result of a Freedom of Information Act request.
Namely, that the narrative Obama has been telling about the first two years of his life is a lie. His mother and father never lived together with Barack Jr. as a family. She went to Washington State. Obama Sr. stayed in Hawaii and left for Harvard before the future president turned one, not when he was two. The marriage itself might be in question.
Everyone is consumed by the release of the Certificate of Live Birth, but not with the truth behind it.
Obama is skillfully playing this out, no doubt on the advice of counsel, to divert, dissemble and distract.
