Well, I didn't said that.
Let me give you an example:
The mosaic dir can be as an instance /path/to/mosaicconfig, containing
indexer.xml datastore.properties and _auxiliary.xml file.
The same folder may also contain netcdf datasets. However, in case the
rasters are into a different location, as an instance on
/path/to/netcdfdatasets, just make sure to add the IndexingDirectories
parameter to indexer.xml, referring to /path/to/netcdfdatasets.

You just need to configure an ImageMosaic coverageStore by indicating
/path/to/mosaicconfig as URL parameter.
http://docs.geoserver.org/latest/en/user/_images/imagemosaicconfigure1.png
GeoServer will create an ImageMosaic on top of that folder, checking the
configuration available in the related configuration files so it will also
parse the IndexingDirectories parameter (if specified), resulting into
looking for raster files somewhere else.
In case you need additional clarifications, you could consider checking
this tutorial too which provides some more details about multidimensional
mosaics:
http://geoserver.geo-solutions.it/multidim/en/index.html
Hope this clarifies a bit the topic.
Please, let us know if you still have issues.
Cheers,
Daniele
