redirect_to != return

Question

I\'m looking for some clarification regarding the behaviour of redirect_to.

I have this code:

if some_condition
   redirect_to(path_one)

From http://api.rubyonrails.org/classes/ActionController/Base.html:

If you need to redirect on the condition of something, then be sure to add “and return” to halt execution.

def do_something
  redirect_to(:action => "elsewhere") and return if monkeys.nil?
  render :action => "overthere" # won't be called if monkeys is nil
end
