They probably meant something like "echo > logfile".
They probably don't. Actually echo is both unnecessary and might even annoy some log processing applications.
is just telling the shell to redirect the "null command" to that file, which has the wanted side effect of clearing its content.
If one is uncomfortable with this terse syntax which might look like a syntax error to someone familiar with it, any command with no output can be used instead like:
or even the famous
that many people think have some black magic power which it certainly has not.

Just deleting the logfile with rm doesn't work as expected since, if the file is still open, it will continue to exist on disk until closed.
Absolutely, a common mistake leading to "why is my disk still full while I've removed the big files from it" so frequent question.

logsave
LOGSAVE(8) System Manager's Manual LOGSAVE(8)NAME
logsave - save the output of a command in a logfile
SYNOPSIS
logsave [ -asv ] logfile cmd_prog [ ... ]
DESCRIPTION
The logsave program will execute cmd_prog with the specified argument(s), and save a copy of its output to logfile. If the containing
directory for logfile does not exist, logsave will accumulate the output in memory until it can be written out. A copy of the output will
also be written to standard output.
If cmd_prog is a single hyphen ('-'), then instead of executing a program, logsave will take its input from standard input and save it in
logfile
logsave is useful for saving the output of initial boot scripts until the /var partition is mounted, so the output can be written to
/var/log.
OPTIONS -a This option will cause the output to be appended to logfile, instead of replacing its current contents.
-s This option will cause logsave to skip writing to the log file text which is bracketed with a control-A (ASCII 001 or Start of
Header) and control-B (ASCII 002 or Start of Text). This allows progress bar information to be visible to the user on the console,
while not being written to the log file.
-v This option will make logsave to be more verbose in its output to the user.
