Dozy, BOAC said "modes" and you responded with LAWS.
I'd read more carefully.

I refer you to the table (matrix) of A330 flight laws that was quite popular, though it is vintage 2005, as discussions on this mishap began.

I'd invite you to look at that chart again.

There is an interaction between behaviors a laws and which protection does or doesn't turn on or off or is modified, see the notes.
These modes include all that ... with varied PROTECTIONS

PITCH ATTITUDE
LOAD FACTOR
AOA
HIGH SPEED
LOW ENERGY
LOW SPEED STABILITY
HIGH SPEED STABILITY
ANGLE OF BANK
MAN’UVER LOAD ALLEVIAT-ION
TURBUL-ENCE DAMPING
YAW DAMPING
TURN COORD
NORMAL LAW
ALTERNATE LAW 1
ALTERNATE LAW 2 (with subtle degrees ...)
DIRECT LAW
MECH BACKUP

If BOAC had meant "laws" I suspect that's what he'd have said.

The picture he was trying to paint was of the complexity of what a pilot faced in knowing what he can expect his plane to do, or to be able to do.

That's how I read it anyway.
