What does "the sha256 value of <hexvalue>" mean?

For example, in a repository with two objects:

 1. an object with sha1-name abcdabcdabcdabcdabcdabcdabcdabcdabcdabcd
    and sha256-name ef01ef01ef01ef01ef01ef01ef01ef01ef01ef01ef01ef01ef01ef01ef01ef01

 2. an object with sha1-name ef01ef01ef01ef01ef01ef01ef01ef01ef01ef01
    and sha256-name abcdabcdabcdabcdabcdabcdabcdabcdabcdabcd...

what objects would you expect the following to refer to?

  abcdabcd^{sha1}
  abcdabcd^{sha256}
  ef01ef01^{sha1}
  ef01ef01^{sha256}

Thanks,
