We don't have the RO and softener drains connected together, it would be possible but you may need a check valve on the RO drain to stop the softener drain flow entering the RO. Certainly on the WRO-300.
It's debateable whether the RO needs it as it has its own air gap in the break tank.
There's no air gap on the softener so these devices work well for making the drain connection, also they give a good jet wash down the upstand during regen so may help to keep the pipework clear.
