Its not really a contradiction,
(i) the holder of a licence may log as PIC time all of the flight time
during which he or she is the PIC;
a pilot on a test is operating the aircraft as directed by the Examiner who is legally PIC; therefore thay are not PIC, but PIC under supervision. The UK CAA accepts this but the regulation does not.
SPIC is specific to an Integrated course where a student can only practice IF with an instructor on board.
