>From the Emacs manual:

  ‘x’
       Download and install all packages marked with ‘i’, and their
       dependencies; also, delete all packages marked with ‘d’
       (‘package-menu-execute’).  This also removes the marks.  If no
       packages are marked, this command will install the package under
       point (if it isn’t installed already), or delete the package under
       point (if it’s already installed).

The doc string says similar stuff:

  If no packages are marked, the action taken depends on the state
  of the package under point.  If it’s not already installed, this
  command will install the package, and if it’s installed, it will
  delete the package.

So this is documented behavior.  This is not a bug, but a feature.
