Just imagine a piece (say, a waltz by Johann Strauss[*]) that has not a single segno, but a bunch of them. It might confuse an orchestra if the conductor asks to start 'at the segno' during a rehearsal – from experience I can tell you that at least one musician will ask 'which one?'... In other words, it actually does make sense to have both rehearsal marks and segno signs at the same position. Werner [*] A concert waltz by Strauss normally consists of an introduction, five (sub) waltzes, and a finale/coda. In German this is called a "Walzerkette".
