Yes, I have done it... to include step 4 and 5. Step 5 has you retrim before turning the switches off. If you do it wrong you have to work harder, but the plane is controllable, unless you skipped step 4 as well.
There had not been a runaway stab in many years. SWA didn't even have it as a memory item anymore, but they were still expected to know it. The Stab Trim cutout did occur after the first "if runaway continues", but I bet you never read the notes. It still told you to trim before turning them off.
