Locking the differential (diff) would likely be explained better by brian, but I'll try my best. Basically, the diff wont lock until the inside tire(s) start to lose grip. That being said, in rain tires will lose traction sooner than on dry pavement. Therefore, the ACD will have to engage locking the diff sooner to keep power distributed properly.

Evo is 50/50, 24/7, 365, always
ACD modes only change the limited-slip properties of the center diff.
" Active Centre Differential
Using sensors, ACD regulates slippage in the 50:50 torque-split diff from free to lock-up according to speed and load. So under hard acceleration the ACD moves towards lock-up to put more torque down on the road for stronger traction, but with rapid steering inputs it operates virtually like an open differential to improve steering feel and response.
A choice of three setting - tarmac, gravel and snow - operated manually, gradually lock up the Active Centre Differential depending on road conditions."
