Out of interest, how many 01 and 10 runways exist worldwide?
If the automation identifies that the aircraft is lined up on a different runway to the one that you have calculated for then it should provide a warning. If you are on a taxiway the alert should not be given if you have entered a runway to taxi to another (this is common at some airports) then you would get the warning and cancel it not a real problem.. If I remember correctly this type of warning was also proposed after the Comair crash taking off from the incorrect runway at Lexington Blue Grass. While confusing numbers don't help they are not necessary, worldwide departures from incorrect runways are unfortunately quite common.
