The phase of a signal generally refers to the timing of the signal (or how two sinusoids line up) as you posted in your question. But you are asking about the phase of a signal in the frequency domain (i.e., after an FFT operation). The FFT function computes an N-point complex DFT.

Phase Spectrum − – The plot of the phase of Fourier coefficients versus frequency is called the phase spectrum of the signal.
Read moreWhat is the difference between magnitude and phase?
The magnitude corresponds to the frequency of the size wave, and the phase corresponds to where it hits zero .
Read moreWhat is the phase of a signal?
The phase involves the relationship between the position of the amplitude crests and troughs of two waveforms . Phase can be measured in distance, time, or degrees. If the peaks of two signals with the same frequency are in exact alignment at the same time, they are said to be in phase.
