Hard to say... I wasn't alive at the time, and the article-writer (the pilot) didn't mention it, other than a higher app/landing-speed...
I have worked 40 years with a BS in Aerospaace Engineering and know that you can't apply speciific ideas to all aircraft in general. The "thin supersonic wing" concept is a fact and not a theory.

as an adendum, L. E flaps are powered up and down either hydraulicaly or electrically where slats are designed to be extended and retracted by airloads depending on the airspeed and the angle of attack.
Not to step on your toes or anything, but every source i can find says otherwise....
Here's the basic definitions:
Slot:
A permanent slot in the L.E. of the wing. The slot is designed to energize the boundary layer, delaying the stall. By delaying the stall the wing is able to fly at a greater angle of attack thus achieving a greater CLmax.
Slats:
Slats give the same advantages as the
Slot, but can be extended for takeoff and landing, either mechanically or aerodynamically, to achieve the same effect as the fixed slot shown above, but to still have the advantage of a "clean" wing during cruise.
L.E. Flaps:
L.E. Flaps perform a similar function to
Slats. The difference is that leading edge flaps increase the camber of the wing, and do not create a slot. As a result LE flaps increase lift at all angles of attack, and do not delay the stall as effectively as slats.
Based on these definitions, i give you this list of examples:
Aircrafts with Slots:
Saab MFI-15 Safari
Zenithair STOL CH701
Dornier DO.27
Dornier DO.28
Aircrafts with Slats:
Aerospatiale Rallye (Actuated aerodynamically)
DC-9
MD-80
A320
Boeing 737 (has L.E. Flaps between the fuselage and the engine)
Boeing 767
Panavia Tornado
Aircrafts with L.E. Flaps:
Boeing 707
Boeing 727
F-16
F-18
Hope this will help you understand the difference....
