"When the function or command is invoked, the
first argument ($1) is the name of the command whose arguments are  be-
ing  completed,  the  second argument ($2) is the word being completed,
and the third argument ($3) is the word preceding the word  being  com-
pleted on the current command line. "

So your echo command is echoing the arguments it receives when invoked by
the completion system.
