"Easy" is a relative term. Not everyone here, especially in the "General" forum is comfortable yet with flashing alternative recoveries or using abd, etc. This is meant for the novice and/or purist who does not want to alter the phone in order to receive and apply the update. This method does in fact work. Quite often the device is ready to receive the update, but the built in automatic & manual checkin fails to trigger the process. Clearing the GSF data forces the device to initiate it almost immediately, as opposed to waiting an undetermined amount of time for the device to resolve the issue on its own.
My advice to the audience who this is intended for: If this did not work for you now, try it again in a few hours or tomorrow, I assure you it will be much faster than waiting for it to happen naturally. In fact, to prove my point further, go ahead and try the manual checkin (under settings > about phone > system updates) first, each time, before you try this. You'll eventually see what I mean. FYI - Every Nexus device has behaved this way.
