yes, but did not sauron take control of those lands? and maybe only one was caught. perhaps the other may have been tainted and placed in the watchers. and look at it this way. as you have said, "Sauron would have put them to better use than guardians of Cirith Ungol". if my theory is correct, perhaps they were like the seven dwarves. weak enough to taint, but too strong to take control of.
