No, RM means a person can only use it for the specified agreed use. For instance, you sell it for a 1/4th page inside a magazine that prints 50,000 copies. It can only be used for that and only once, it can not be used in another magazine, or in a website, book, poster, whatever, it can not be used in a full page or in the cover, and it can not be even used in the same magazine again. Hmm, did I forget something? Oh, yes, a period of time for the license may also be set, as well as geographical restrictions.
The price depends on the usage. For a book cover it costs more than for a 1/4th inside page. For a magazine issue with 100,000 copies it costs more than for one with 20,000 copies. A worldwide license costs more than a single country license.
In RF people can use the same image over and over again (depending on the case, in microstock an EL would be required), so in fact a RF image should cost more than a RM.
