The _only_ information it gives is that the hydrogen bond exists only 3
out of every structures in your ensemble. If you want an explanation as
to _why_ they hydrogen bond breaks, you will need to do further analysis.
Both of your explanations seem reasonable, but based on just the hbond
analysis it is entirely speculation.
