Someone else could probably explain this better, but I'll give it a shot.
GDAL is a library which other programs can leverage, this is the
libgdal* packages. If you have multiple libgdal packages installed
they won't interfere and applications are usually set to use a certain
version of the library.
But GDAL also ships with some command line utilities like gdalwarp,
gdalinfo, etc. which are in the gdal-bin package. The version of
gdal-bin controls which version of these utilities are installed (and
which gdal library version the utilities use)
