A question about using portsnanp to upgrade ports tree

[Nan Xiao]

Hi all,

Greetings from me! I have a question about using portsnap. 

After reading Using the Ports Collection in handbook, per my understanding, if /usr/ports/* is not empty
after installing FreeBSD:  

/usr/ports # ls
.arcconfig      Mk              audio           distfiles       hebrew          multimedia      print           x11
.gitignore      README          benchmarks      dns             hungarian       net             russian         x11-clocks
.....

I only need to use "portsnanp fetch update" to upgrade ports tree, no necessary to do "portsnanp fetch extract".

Is my understanding right? Thanks very much in advance!
