The problem is that when you cold boot your Amiga (warm boots are not a problem), it is not booting OS 3.9 ... it's booting from the ROM, which should be OS 3.1, first. OS 3.9 doesn't technically get loaded until SetPatch executes at the beginning of the startup-sequence. So, it's OS 3.1 that cannot handle the >4GB boot partition.
This does not apply to the CPPC SCSI, which has a TD64 scsi device driver in its bios which is always 64 bit aware. Filesystem isn't a problem either, since this is loaded from the RDB prior to the OS being bootstrapped.
The problem could arise that OS3.9 then goes on to patch the same driver to be NSD...which it doesn't need to do.
