1. Because it's a useful working example, unlike many others
2. I actually do just that sometimes. eg I cat a file and discover it's 
too long, so I back up and pipe it into less (or grep or awk or tail or 
head or head and tail).

Sometimes "cat  file|" is clearer than " <some very long command> <file"

eg
cat /etc/passwd | awk "/$USER/ {print \$0}"

Of course, the awk program could be quite a deal more complicate than that.
