Correct.  “No updates” means that the current (installed) version is
more recent than any other.

On the screenshots the second number is the candidate version.  This is
similar but not exactly the same thing as "the latest version available
in configured repositories".  From the users manual:

  [The candidate version is] the version of the package which
  would be installed if Package → Install (+) were issued on
  the package …

When the currently installed version is more recent than any other that
version is also the candidate regardless of what is available in apt
repositories.

Does that clarify things for you?

Title:
  aptitude doesn't correctly report the version of packages available
  within repositories

Status in “aptitude” package in Ubuntu:
  Incomplete

Bug description:
  Assume only standard Ubuntu repositories configured:

  apt-get clean all
  apt-get update
  apt-get upgrade
  apt-get install vlc

  should clean all repository caches, update the package databases, then
  upgrade all available non essential packages and finally install vlc.

  Now you are working with vlc and something does not work as expected.
  You are trying the latest nightly packages from the videolan project,
  by adding their repository, by adding a file to
  /etc/apt/sources.list.d holding:

  deb http://ppa.launchpad.net/videolan/master-daily/ubuntu trusty main
  deb-src http://ppa.launchpad.net/videolan/master-daily/ubuntu trusty main

  after doing

  apt-get update
  apt-get upgrade

  the latest nightly builds of all vlc-packages are installed and you
  start testing. Next you remove the added repository, by commenting the
  lines in the above added file out. Then

  apt-get clean all
  apt-get update

  Calling aptitude after will show no updates available. Searching for
  vlc will show the same version as installed and available in the
  repositories! This is wrong, since the version installed came from the
  videolan project nightly build and the repository given was disabled!
  aptitude shall show the version available now not the one installed!
