[Active] Mechagon HC, endless runs. NO LOCKOUT

(Not sure if bug or intentional)
Today I finally decided to try out Mechagon HC.
After doing one part of it I wanted to group up for the second part, however I noticed that I could queue them both up again.
Currently I've killed King Mechagon 4 times in one day, getting loot everytime.

So to test my theory I decided to do The Nexus HC in Northrend and also Freehold HC through "specific dungeon" tab.
I got a daily reset lock on them both but not on either of the Operation: Mechagon parts.

I'll provide 2 screenshots before and after I've done Operation Mechagon.

and after.

As you can see there is no lockout for Operation Mechagon on HC, specifically queued through "Specific Dungeons".
A great way for farming the pets and mounts that drop from these dungeons.

Please do tell if this was intentional and I'll delete this post.
