I think you have found your reason ;-)

A couple years ago I tried to setup something similar but found that I 
had to create separate storage and pools. With this setup I could use 
both drives at the same time (different jobs of course). I was able to 
spread full backup jobs evenly between the two drives and cut backup 
times in half. Which in my case was to cut full backup time down to 
about 20 hours.

Job {
     Name = Job-1
     FullBackupPool = Full-1
     DifferentialBackupPool = Daily
     IncrementalBackupPool = Daily
}

Job {
     Name = Job-2
     FullBackupPool = Full-2
     DifferentialBackupPool = Daily
     IncrementalBackupPool = Daily
}

Storage {
     Name = DDS4-0
     Device = DDS4-0
     ...
}

Storage {
     Name = DDS4-1
     Device = DDS4-1
     ...
}

Storage {
     Name = DDS3-0
     Device = DDS3-0
     ...
}

Pool {
     Name = Full-1
     Device = DDS4-0
}

Pool {
     Name = Full-2
     Device = DDS4-1
}

Pool {
     Name = Daily
     Device = DDS3-0
}
