OK - I'm well up to speed on my Freelander 1 - tyre matching/VCU monitoring/IRD wrecking etc - but a total newbie on the FL2.
Question 1:-
Is the normal Haldex road-going mode not pure 2 wheel drive other than at take-off?
And so - is tyre matching as critical as on the FL1 - I know it's still good practise but there is no mention in the handbook of new tyres to the rear etc as there is on FL1
Does the Haldex control recognise a difference in wheel speed as small as generated by say a difference in tread depth of 4mm front to back - and would it re-act differently to the same difference back to front? If not it would be just as bad "new on rear" as "new on front"
Question 2:-
Is there a gearing difference front to back as in the FL1?
 
Personally I'd always try to keep an AWD vehicle tyres the same, or similar diameter. It's probably less critical on an electronic AWD vehicle, but the Haldex can hardly be called indestructible, so I'd keep all tyres the same.

Haldex will take out the difference with some slip but it is still preferred practice to put newer deeper tread tyres on the rear. Due to its always potentially "active" nature of switching in the 4x4 when it needs too, yer still need to be careful with tyres.
