It seems that insync does not sync the multiple copies of a given file or folder. In Google Drive, one can use shit-z on a file or folder (web interface) to create an alias of that file or folder elsewhere - which is very useful because there are often several places to store a file. So this alias possibility is very interesting.
With the Google sync utility, the multiple copies are synced locally, which is the desired way of working (one wants to access files and folders in whichever location they are, and since they are synced, the multiple local versions are always kept in sync): http://note.io/1ypkpNR
With insync, they are not: http://note.io/1a6EL9t
