An author's copyrights can be assigned or transferred to a third party. This leaves the author with only the same rights as any member of the general public. (There are a few narrow exceptions, but nothing that would prevent the possibility of an author infringing on the copyright of a work he created)
It's also possible for a person who prepares a work to not be considered the author. This is the case for works made for hire.
And of course copyright isn't mandatory, though that just leads to works being in the public domain, so at least there's no danger of infringement there.
