Too add some details:

The Release file for experimental contains:
NotAutomatic: yes

This causes apt/aptitude to automatically pin experimental to 1 (I
think).

Then, when installing/updating apt will look at all sources of a
package, take those with the highest pin and of those the one with the
highest version.

For more RTFM.

PS: If unsure run apt-cache policy [package] to see what apt things.
