From the photo's it's not possible to say whether the honeysuckle was growing over the fence before it came down or not. So on that basis every reply, including this one comes with a lot of "ifs" and "buts".
The comment about the cut edged of the laps being upwards really doesn't make sense as we are seeing the back of the fence so of course the cut edge is up - it's down on the other side. Also the fence does have a capping piece on each section and that is intended to be on the top which it is.
Is the fence a boundary fence or constructed on the neighbours property. If on his property you would have no right to grow anything up it.
An evergreen honeysuckle can have a lot of weight to it particularly given the heavy rain we've had lately so that on one side of the fence could have an effect.
I can't see anything which shows definitively how the posts were retained.
All that said, the fence posts do look pretty old and I would suspect that the failure is down more to weather and age.
