followup storage question

[William A. Mahaffey III]

The Wiki page https://wiki.freebsd.org/RootOnZFS/GPTZFSBoot/9.0-RELEASE 
illustrates using gnop to enforce 4K alignment of gpt partitions for 
subsequent use by ZFS. However the gpart commands also use the '-a 4k' 
arguments, aligning partitions on 4k boundaries as I understand things. 
Is the gnop command also necessary ? TIA & have a nice weekend.
