Hi Ludmil...
1) if you take a look at the thread I point at in the first response....this is addressed.
2) additionally, as Walter points out, if you import sequence revisions via Media Browser...it should avoid asset duplication.
points 1 and 2 work together: if you use the XMP tagging pref, the asset is more likely to be properly recognized as existing in the project by PPro.
The big point is that
1) pref should be enabled brefore importing any assets into a project (so they'll get tagged)
2) 2 editors down' work on the same project, but 2 projects using the same asset set.
A) import assets
B) dupe Project as editor B
c) import editor B's work into A's via Media Browser
