Can you quote the rule please? I really don't think European legislation works like this, since many operators in Europe interpret this in a completely different way. Two tickets = two contracts independent of each other. It is possible that national legislation in some member states treats it differently, but in general it does need to be a through ticket for connection to be protected.
