it should, see

but it's not completely unsynced as the man page states (we should probably 
remove EXPERIMENTAL)
"
--asynchronous-upload
(EXPERIMENTAL) Perform file uploads asynchronously in the background, with 
respect to volume creation. This means that duplicity can upload a volume 
while, at the same time, preparing the next volume for upload. The intended 
end-result is a faster backup, because the local CPU and your bandwidth can be 
more consistently utilized. Use of this option implies additional need for disk 
space in the temporary storage location; rather than needing to store only one 
volume at a time, enough storage space is required to store two volumes.
