There usually isn't more that one aircraft at say your 11 o'clock two
miles.

In a relatively busy airspace, there may well be more than one aircraft
close enough to the 11 o'clock at two miles for there to be a question.
Clock directions are very low precision, due to the facts that there's 30
degrees between each direction, ATC doesn't actually know your heading, and
all of the traffic is constantly in motion.
