That dragons may have an impulse to fly out of weapon range when actually threatened, in which case having a way to reach a dragon in the air is very useful?
That's a reason they'd like to use a ranged attack once in a while, but not a reason that they'd worry about a rapid-fire of two arrows in specific. Why not an attack that disables flight for a time, or an ability that lets them cling to a big creature when it moves away? What is it specifically about dragons that makes a double ranged attack a good thing to use against them in particular?

1. More dakka
2. More damage against large and larger creatures
3. Usable at range, so a really good option to have when fighting something that can easily keep out of range of melee, like dragons.
Why not just "make another attack?" Why make it have to be ranged? Why not pump up the damage bonus to +whatever against Large creatures instead of having to make the second attack? The alternative to this ability isn't nothing, it's an ability that is better suited to the story of "I kill dragons" than making multiple ranged attacks is. Which might be "Do a bunch of extra damage and also if the creature can fly, it can't fly for a round."
There is nothing about "I shoot two arrows at it" that makes me think the character is fighting a dragon.
Hunter's Veil suffers the same problem.
Alternatively, Uncanny Dodge makes sense: you avoid breath weapons easily. Slayer's Momentum, too: you deal extra damage because dragons are big and have piles of HP. Even the "more damage to a Large creature" makes sense. But there's nothing about "I shoot it twice" or "I can hide" that makes particular sense with what we know about dragons. The Horde Breaker is overall much better, making a lot of sense in terms of fighting multiple creatures - even Slayer's Hands is fine: extra attacks for extra critters. But Pack Awareness is also in the same camp.
The abilities need to relate to the creatures more closely. "I shoot it twice" makes sense for a creature that tends to fight at range (I'm thinking a "Mage Slayer" path for thwarting spellcasters), or for a more thematic animal hunter style (Ranged attacks are typical hunting weapons). "I prevent surprise" makes sense for a creature good at surprise (a hunter of predators, for instance). "I can hide" makes sense for a creature good at seeing precieving you. Heck, they'd all make much more sense as a "Hunter of Beasts" path than they do in their current camps.
There's not much about fighting dragons that you'd think "What would be really good is multiple ranged attacks." While you might want to launch a ranged attack when the dragon flies, dragons aren't stereotypically fighting you on the wing, so it's kind of a corner case.
