As mentioned in the upload guidelines:

This is the case with your upload. The airframe is delivered to Omega Air and received a new registration. Since this is not a new type for Omega, only the first accepted photo is considered as hot.

The example you gave concerns a new aircraft type produced by the manufacterer, which wasn't in the database. The guidelines state the following about this:

Therefore the 48 hour rules applied and three shots were accepted as hot as they were uploaded within 48 hours after the first one was accepted.

Hope this clears up the situation.
