Yep.  That's dead on.

Tight curves have inductance, a lot more than gentle curves.  Lightning currents start and stop very abruptly, which correpsonds to a lot of high-frequency energy.  So even a LITTLE inductance in your wire and it would rather jump through the air to something else.

That's why you put a lightning arrester on your antenna cable just before it goes through the wall (keeping things straight or gently-curved from the antenna to the arrester and the arrester to the ground rod), then put a rather tight J-shaped loop in the cable just below the arrester as it goes into the wall (sorta like the trap under your sink, but a bit smaller).  The "drip loop" makes the lightning reluctant to go through the wall, increasing the fraction that goes to ground through the arrester and greatly reducing the amount that goes into the house and tries to kill your radio or TV.

(It's called a "drip loop" because it also leads the rain down to the bottom of the loop where it falls off, rather than following the wire into the wall and rotting the house.)

This high-frequency equivalence also makes the lightning tend to travel mostly on the SURFACE of the wire.  (It's called the "skin effect", and it's why you can take hits from a tesla coil on a conductor you're holding and have the current go through your body without even noticing it.  Good if you're hit by lightning - because most of it doesn't go through the core of your body, which is why lightning-strike victims often survive rather than exploding.)
