This might not have been clear from my statement but this is not based 
on a particular local situation in Germany but comes from looking at 
data worldwide.

man_made=embankment is almost exclusively used for one-sided artificial 
slopes - prominently supported by OSM-Carto rendering it this way.

barrier=embankment is in the relatively small volume of use mostly used 
for symmetric structures with slopes on both sides.

And current tagging documentation does not provide a clear suggestion 
how to tag such - if with embankment=yes as a standalone tag or with 
man_made=embankment + embankment=both or embankment=two_sided.
