the thing is that there are the IFAB's Laws of the game, which are the same everywhere.
and the other thing is advices (or whatever they are called) from UEFA, or FIFA, or any national federations for their competition.
The one that i mentioned already, that refs should always decide in favour of the attacking team when in doubt, there's this one that the Refs should protect the keeper in its own area. In WC2002, referees were advise to sent-off divers instantly as they were advised in this Euro2004 to sent-off players which had violent tackles.
There are refereeing commitees that study what should be the refs conduct during a game and how should they do their decisions in technical terms and discipline. This particular "rule", which is not really a rule, more like an behaviour refs should have, is applied in UEFA competitions, if you dont believe me, watch the next games and future games, and im sure will get some similar situations in the goal area, in which the ref decides in favour of the keeper.
Even with one of the most prestigiated refs in the world saying it, isnt enuff for you to believe what ive been saying about this? RaGe said it too, if u consider him more trustable

And i said it before the ref mentioned it, so i cant possibly be making that up.
EDIT: and, at least here in Portugal, english football is considered to be much more physical and that the referees are way more compliant to contact, which to be honest, i think its a good thing, but that doesnt change what UEFA thinks.
