Dominion spread into enemy territories?

[PhilD]

I've been reading the Dominion chapter of the manual pretty carefully, and have a few questions that some of you may be able to answer

* dominion spread: the manual says that when a "dominion spread" occurs (not produced by preaching), either the local dominion will increase, or enemy dominion will decrease, or it will be "passed" to some randomly chosen neighbouring province. Does this mean that each successful "temple check" will result, somewhere (potentially far away) in a dominion increase (or enemy dom. decrease)? (My past experience was that the effect didn't seem to be that radical)

* order of things: since dominion increase don't "leak" to other provinces, the order in which things happen can be important - as is the interleaving of these actions between nations. Is this specified somewhere?

(What I mean is that, if preaching happens first, successful preaching can make it easier to get a successful temple check, which in turn might leak to adjacent provinces; while, if preaching occurs last, it's more likely to be "wasted" as previous temple checks - and leaks - could have increased dominion to the limit before it happens. Also, enemy dominion spread can change conditions, so the question of "who goes first" can be important)
