I don't know.

I think it depends on how your definitions match for the extent of the
wetland vs. the extent of the other water body.  Certainly tidal water
can be represented differently via high tide, low tide, mean markers,
etc.  If the data is coming from different sources or versions I think
we should be surprised if the edges line up.

Even surveying a wetland along a river would be tricky.  I don't know
how I would decide where one stops and the other starts, or if they
overlap.
