I've toyed around with doing that in the past as well -- mainly when making a live USB to a stick bigger than 4GB. Using the separate "casper-rw" partition enables you to use a persistence file bigger than the normal 4GB limitation. Only difference from what you've done is I used "ext2" file system on the casper partition. Ext2 doesn't cause as many write operations to the partitions due to the journaling feature of the "ext4" format and (in theory) that may extend the life of the flash drive. (Don't know if that really makes much of a difference or not though. I just went by what I read in various places.)
Also, I believe I used UNetbootin when I did that instead of USB-creator-gtk; but as long as your method is working for you, no need to change it. Both are similar. Process-wise, if memory serves me right, I also made live USB first, then shrunk the partition on the USB and made a large new one labeled "casper-rw". Don't remember if I bothered trying to make the casper partition ahead of time as a comparison or not. If you do try that, don't label it until after you make the live system in the FAT32 partition and delete the existing casper-rw file.
Yes -- I've run into the same problem a few times, but haven't had the time to fiddle around in effort to track down what's going wrong. I don't remember my exact situation(s) when that happened, but am pretty sure it happened only when trying to shrink existing partitions on USB's. I think I ended up just deleting all partitions and then creating them over again from scratch in GParted -- that seemed to work. No idea why it wouldn't do the shrinking and not sure when I'll have time to play around with it more to try figuring that out. (If I do find an answer somewhere along the line, I'll post it back here.)
For you, solution might be to create both the FAT32 and Ext2(or 4) partitions on the USB ahead of time. Make FAT32 partition about 800-850GB so you can make a small persistence file on it with USB-creator-gtk. Don't label the Ext2 partition. After creating live system in FAT32 partition, delete casper-rw file and then label the Ext2 partition as "casper-rw". I think that will work.
