Since ISS is unlikely to hear ANDE, why not be a bit more explicit and reduce the likelihood of the sats colliding with eachother (transmissions, not the sats themselves, hi)? I'd use a path of APRS via RS0ISS-4,ANDE-1.

ANDE is catching up to ISS. Now at about 0100z on the 5th, ANDE's footprint is just touching ISS's. And ISS is on packet on 145.825 just like ANDE.
Over the next several hours, ANDE will get closer to ISS and then move out in front.
I suspect that ISS has no chance at hearing the weak ande, and ANDE might not hear ISS, but the best chance will be monitoring ANDE's downlink for any double hop packets via ISS.
Since both spacecraft respond VIA ARISS, then a double hop packet might try the path UNPROTO APRS VIA ARISS,ARISS. A slightly more efficient path (shorter packet) might be APRS VIA WIDE2-2.
