It's supposed to collect the fuel vapor/fumes instead of allowing them to float into the atmosphere. It's probably much more prevalent in areas that get hot (causing fuel to evaporate) or maybe very low humidity.

I remember as a kid, if you filled a car REALLY full and then parked in full sun in the summer, it was possible for the fuel to expand due to the heat enough for fuel to weep (pour) out of the fuel inlet around the cap seal.
