The segmental ordering within the sublayers of a lamellar polystyrene-poly dimethylsiloxane-polystyrene triblock (PS-PDMS-PS) is examined by NMR. The carbon and deuterium NMR line shapes of the PDMS sequence (soft block) reveal clearly a wide distribution of segmental orientational order S in the lamellae and thus a distribution of constraints probed by the chains. It is observed that this distribution is mainly due to the coexistence of positive and negative S, resulting from a competitive ordering effect induced by the presence of glassy interfaces ($S < 0$ in their vicinity) and the chain-end anchoring junctions ($S > 0$)
