Just reread my logic. I believe I am correct. I may need to explain it better. Let me know if what I said makes sense.
Yes, you have it right. Congratulations.

Spoiler:
In fact, using the method you propose (which is the right one) you always tie with the Gaoler, and so go free. It's not possible with this method to end up with more heads than the gaoler.
