This is, as Eric Blake noted, required POSIX behavior.  As to the manual:

        If  a  non-
        empty  directory  name from CDPATH is used, or if - is the first
        argument, and the directory change is successful,  the  absolute
        pathname of the new working directory is written to the standard
        output. 

This is from the description of `cd'.

`pushd' and `popd' are documented to run the `dirs' builtin upon successful
operation, and dirs will print the directory stack.
