# How does two inverting op-amps phase cancel eachother out?

When doing a frequency sweep simulation of the circuit below in CircuitLab, I can see that at $V_{out1}$ there is a phase invertion and at $V_{out2}$ there is not. I know that the inverting amplifier do phase shift by 180 degrees and that two of these cascaded will give a 360 degree phase shift that equals to 0 degrees and a delay. What I don't understand is how the two inverting amplifiers cascaded "cancel eachother out" when looking at the frequency sweep. Can someone try to explain this to me?
