It is (was ) a good way to know if the battery was charged - it is not perfect but it is a lot better than going by unloaded voltage which is the way many folks try to tell if a battery is fully charged.
Actually the unloaded voltage is probably the best way to tell the state of charge for a sealed lead acid battery and is a technique used in electric cars. The relationship for charge and voltage is linear. Granted you can't run a load off the battery for at least fifteen minutes or else you can't get an accurate measure of the charge but otherwise this is a perfectly valid technique. Nickel metal hydride batteries on the other hand only show a measurable change in voltage level when you've pretty much destroyed the battery. You can't use this technique for that battery chemistry.
