I can't make any sense of your drawing, it looks like it starts with you having only outbound liquidity and no inbound.
That's not a re-balancing issue, that's just having initiated two channels. You can't circularly route across your own channels if you have no inbound liquidity at all.
If you wanted each channel to have both inbound and outbound liquidity from that state, you'd either lease a 3rd inbound channel and re-balance the other two with that, or, submarine swap out to chain from either of those channels to free up some inbound.
If you spent down one of the channels organically and the outbound was drained from it, and the other was still unused and had no inbound, then you could circular route to make them even.
