SQL 2012 cluster SP and updates installation

Hi, 

How to apply updates to SQL 2012 cluster? Is it true:

1.  Apply the hotfix or SP on pasive node N2
2.  Reboot the passive node N2
3.  Failover on SQL resource : the passive node become the active node
4.  Apply the hotfix on the passive node N1
5.  Reboot the passive node N1

thanks,
