I found that if I skipped the death dialogue of Jondar with the space button, the templar's killing strike didn't actually kill Jondar. This may have been because Jondar was still in his "pleading" animation before death, or whatever you'd like to call it.
After this, I was able to shoot(with my demon hunter) and deliver the final blow to Jondar, which the Templar's previous strike did not.
