Hope you meant by BlobTempStoragePath and BufferTempStoragePath properties.
These properties will help store your Blob and Buffer storage in case File Syste, / SQL Server doesn't have capacity to hold the data.
Detailed info about these parameters here:

http://www.bimonkey.com/2008/04/blobtempstoragepath-and-buffertempstoragepath/

If you have 2/4 paths, then the single advantage is that if one path gets filled completely the others will be utilized.
If the first path is not completely filled, there is no difference in having either 2 or 4 paths.

Please note that these paths will be used when your MDF file is completely filled ( If autogrowth is restricted) or Physical disk is full or the File system in which BLOB files are stored has no free space.
Hope this clarifies
