You can check earfcn will change from source to target in rrc reconfiguration complete.

Why 2,3 step here in pscell change procedure?
Actually in NR ENDC ho from source to target pscell indicates pscell change.
Ideally sgnb addition request and acknowledge come earlier during SCG addition procedure.
