How do Legendary monster abilities work?

I've been reading descriptions of some monsters in the Hoard supplement, but I didn't see an explanation for how "legendary" abilities work. Here's an example:

 

Legendary Actions

The dragon can take 3 legendary actions, choosing from the options below. Only one legendary action option can be used at a time and only at the end of another creature’s turn. The dragon regains spent legendary actions at the start of its turn.

Detect. The dragon makes a Wisdom (Perception) check. Tail Attack. The dragon makes a tail attack.
Wing Attack (Costs 2 Actions). The dragon beats its wings.

Each creature within 10 feet of the dragon must succeed
on a DC 20 Dexterity saving throw or take 14 (2d6 + 7) bludgeoning damage and be knocked prone. The dragon can
then fly up to half its flying speed. 

 

So does that mean in between its own turns the dragon basically gets three "reaction points" to spend after players take their turns?

 

Example:

Dragon takes all of its attacks for its turn.

Player 1 attacks dragon

Dragon uses 1 point to make  Tail Attack

Player 2 stealths

Dragon uses 1 point to Detect

Player 3 casts a spell

Dragon doesn't have enough points for Wing Attack left, so it uses Tail Attack

 

Next round:

Dragon takes it's attacks

Player 1 attacks

Dragon uses 2 points to use Wing Attack

etc...

 

Is that even remotely correct?

You are correct, except the Dragon could also use its Legendary Actions at the end of an allies turn. It is not restricted to making them at the end of enemy turns.

 

Legendary actions do not count as reactions. They are out of turn actions that some creatures can take at the end of any other creature's turn - whether an ally, or an enemy.

 

Think of these creatures as having several turns each round, one primary turn that happens on their initiative count, and several partial turns which happen at the end of another creatures initiative count, once they have finished all actions during their turn.

Yes, although rather than detect it would probably use tail lash 3 times on top of it's regular attacks like some crazed bum-wiggling puppy.

Having a number of minions equal to or greater than the number of legendary actions maximizes the chance of alpha striking the PCs (or some of them).

You all realize that the DM doesn't need to find loopholes in action stacking to smack down the party.  If your DM is looking to find maximum advantage against the PC's in every corner of the rules out of the misguided belief that they can be an ass and legit at the same time, then please find a new DM.

Page 6 of the DM Basic Rules should help you out, too.
