Yeah - that's how I assumed it had to work. Wormholes just use sufficient energy to 'pop' a hole into subspace instead of the scrunchie effect and that allows even faster travel. Although You don't need to reach out and pull from the far end, the warp field itself can pull in from its closest point and keep on pulling.
However, you still need a big enough bubble to allow you the ability to avoid objects that are too large for your deflector - a small bubble wouldn't allow time to do this, since you are effectively travelling in a straight line and pulling those objects to you at fantastic speeds. This is where the inconsistent abilities of sensors becomes a problem.
