Init global variables at run-time

Can some one throw more light on this statement=>

 /* Init global variables at run-time, not as part of the declaration.
         * This is required to support init/de-init of the driver.
Initialization
         * of globals as part of the declaration results in non-deterministic
         * behaviour since the value of the globals may be different on the
         * first time that the driver is initialized vs subsequent
initializations.

Thanks and Regards
