Thanks for the reply, but that's not what I'm really asking, I'll explain more in depth.
Albino Dragons have a different spawn mechanic, after the server boot (which occurs a few minutes after the server save, for example: Server comes back online at minute 7, and the boot at minute 3) the first 10 minutes are counted and after that a timer that always restarts after 30 minutes starts counting until the next server save. An albino dragon disappears and may appear at this time, and for 30 minutes it may be alive in one of the 5 locations.
In the video it was clearly at the exact moment that the 30-minute timer ran out and another one started. The previous albino dragon disappeared and the new one appeared. What happened there was that there were 2 great coincidences: it is rare for 2 rounds in a row to occur with an albino appearing (since the chance of spawn is not high) and precisely in the same place, for scripting reasons there was a short interval in which the 2 were there at the same time.
If the 30-minute timer is restarting (minute 13 or 43) there is a chance that the albino dragon will spawn. My question is: If I find one in Ankrahmun's D-Lair, for example, is it worth continuing to check the other 4 spots? In other words, could I end up finding 2 albino dragons in the same round (within the 30-minute timer)?
