The web site does mention that there are two versions of the hardware and that they are not 100% compatible. My guess is that the library is stale. https://developer.mbed.org/questions/6351/Difference-between-EM027AS012-and-EM027B/

I have one EM027BS13 so I tested with sample http://mbed.org/users/embeddedartists/code/app_epaper_EM027BS013/ with the lib http://mbed.org/users/embeddedartists/code/EM027BS013/ Except the ledpower blinking nothing on the screen :-(
