You're not talking about missing the "last" leg; you're talking about missing the second of four legs on one ticket. Miss any leg and all remaining legs on the same ticket are likely to be cancelled.
Agreed. On every airline I know of, your reservation will be cancelled once you miss the last leg (with very few exceptions).
If this was a one-way, lots of FT reading has shown that it should be fine to miss the last leg, if done rarely and you have no checked bags.
