What an interesting contrast. I wonder if there's some regional difference in behaviour, or if it's just a case of mandating something which seems superficially beneficial.
To be clear, if it's an emergency door in a large building where a crush could occur, it will open outwards. But most residential buildings aren't big enough to require that, except for large tower blocks.
Which makes sense, until you get to fire-exit doors in the UK, which all open outwards in work buildings, which they have to by law if the building contains a certain number of people. Hence many small shops/offices will have exceptions.
