I'm reasonably sure it has no effect on bufferbloat. You're not even trying to measure latency in your tests so far, only packet loss, which is completely different. Interleave would tend to increase baseline latency, but probably has no effect on the queue.
Only changing the queue length, or inserting an AQM (which shortens the *effective* queue length) would affect bufferbloat.
