I don't follow your thinking re differences in stretch -- the stretchy one should be what
survives, having stretched and let the other bear the load. What seems to be happening
is that the core is slipping within the sheath, so leaving the latter to take the load.
This points to finding a better-married core & sheath (how many reports of this problem
are there; is it brand-specific?), or a stronger clutch!?
