why would using "sftp" require disabling "vsftpd"?

[Robert P. J. Day]

  again, reading RHEL 7-beta docs and here:

https://access.redhat.com/site/documentation/en-US/Red_Hat_Enterprise_Linux/7-Beta/html/System_Administrators_Guide/s1-ssh-configuration.html

one reads:

"For SSH to be truly effective, using insecure connection protocols
should be prohibited. Otherwise, a user's password may be protected
using SSH for one session, only to be captured later while logging in
using Telnet. Some services to disable include telnet, rsh, rlogin,
and vsftpd."

  never having used sftp before, i'm confused ... isn't sftp simply a
secure ftp client? and if so, why would one want to disable vsftpd? i
would still need an ftp server, would i not? can someone clarify what
that passage is saying? thanks.
