Fuel Pressure Regulator comprehension

Take a look at the attachment. Do I have the correct understanding of these hoses?

Should the FPR continuously be dumping fuel through the return line? In other words, if I disconnect the return line, I start the pump and fuel starts pouring out of here. That's bad right if I'm understanding correctly?
