It's simple etherum algo is memory intensive so it depends on the gpu memory you can underclock the core without change in etherum hashrate , so why not mine a core intensive algo at the same time with etherum ,core intensive means it doesn't depends on memclock but on coreclock so this is how dual mining works , some algos only can be mined with etherum.
