SSD Optimizer, duplication and nested pools

[RottenBit]

I'm having trouble with SSD Optimizer plugin to behave like I thought it was supposed to.

So I did the following with default settings, for both Balancer and SSD Optimizer:

HybridPool consist of 2 nested pools as Archive disks and two SSDs as the cache disk. I've enabled 2x duplication on HybridPool.
- Cache: Local SSD drive
- Cache: Local SSD drive
- Archive: LocalPool (nested pool)
- Archive: InTheCloudPool (nested pool)

LocalPool (no duplication) consist of:
2x Local HDD

InTheCloudPool (no duplication) consist of:
1x CloudDrive via Google Drive (only 1 drive for now)

As I said I've enabled 2x duplication on HybridPool. When I copy a new file (500 mb) to HybridPool the file gets copied to both SSDs. When the copy is done, DrivePool only moves one of the duplicated files from the SDD to the Archive. So the files are now located on one SSD and on one Archive. I want them both of them to be moved to both the archive drives, duplicated, leaving the SSDs empty.

Do you see what I'm doing wrong or is it simply just not possible? Let me know if anything isn't clear.
