How does electronic iteration work in a VASP relaxation calculation?

I am a beginner using VASP to do material modeling, and I'm confused about the following questions:

1. How does the electronic iteration work in VASP relaxation calculation?
2. Is the electronic iteration during structure optimization and the same as that done in a single static self-consistent calculation?

If they are the same, it seems that there is no need to perform a static self-consistent calculation after structure optimization. In the last ion step of structure optimization, the calculation converges and atom position will not change further, electronic iteration at this point should be equivalent to electronic iteration in the subsequent self-consistent calculation.

The figure below represents very well the self-consistent field (SCF) procedure used to solve the Kohn-Sham (KS) equations under the Density Functional Theory (DFT) approach:
