>>It would show you areas that fell within those parameters,
>>not areas that included them.

All of those areas have at least one end of their range within your parameters. If you limited it to areas that fell between both of your parameters, how would you see a great lower level ranking area that also worked well for higher level ranking?

Yup. You hit the nail on the head. Otherwise, why include the higher parameter? If I say - areas 1 5 - and I get a list of areas good for 1 to 30 - what did the "5" accomplish? I understand what the lesser digit "1" accomplished and I see the value of showing more areas as opposed to less, I just don't understand the significance of the "5" in the syntax employed.

Say there is an area that's good for levels 5 to 15; that area will show up if you type in 'areas 1 5'. It won't show up if you type in 'areas 1 4'. That's what your upper-limit accomplished - it brought in the areas that have a lower lower-limit.
