This has the important consequence that a given volume of plasma contained within a flux tube ''remains'' inside the flux tube as it is advected, twisted, and stretched by the fluid flow.

This implies that the topology of the flux tube cannot change due to the fluid flow.

Stated differently, the magnetic flux contained in a volume element of the plasma is carried along unchanged as the element moves.
