And also that these people are less likely to get PTSD in the first place.

It does make clear there is no conclusive direction so it is not known if large hippocampal volume increases resilience or if increased resilience produces a larger hippocampus. What it does say is that after successful exposure treatment there was no significant difference in hippocampal volume. So the treatment does not make it bigger (more resilient) or smaller. Interesting.
