The NLA tracks are basically animation layers. So an animator can have more control over animation layering and have it exported as a one animation when imported into Godot. Exporting from Actions, and each action will always result in separate animations. This makes the NLA editor very powerful.
To give a few examples.
As an animator, your workflow might involve animating a base animation, then creating correction animations layered on top of the base in the NLA editor. When naming the animation tracks the same, Godot will then import these as 1 animation. This way, you can animate non-destructively and still keep your animations organized.
Another example is that if you are animating a longer sequence, you can chop each moment into its own animation track in the NLA editor and then blend them, giving you more control/flexibility in animation "editing" (just like when cutting together video, but here with animations instead) instead of messing around with keyframes manually for a long, messy sequence. Then, by naming the tracks the same, you can export the entire sequence as 1 animation to play in Godot.
Another example would be if you happen to have 2 objects that are meant to be animated as 1. If you create animations and simply export the Actions, they will end up being 2 separate animations instead of the 1 intended.
