Indeed - not separating actual water mapping from mapping geomorphology 
is one of the primary disadvantages of the waterway=riverbank tag (for 
which as said there are advantages too) - and is partly responsible for 
quite a few cases where water mapping covers the whole floodplain of a 
braided river like here:

http://www.openstreetmap.org/#map=12/46.0764/12.8456

Similar situation by the way with landuse=reservoir/landuse=basin - 
acutal presence of water vs. dedication of an area for certain use.
