The observed strong electric fields and currents inside the separatrix region can be important for a local energization of ions and electrons, particularly of ionospheric origin, as well as for magnetosphere-ionosphere coupling.
Strong electric fields exist inside the separatrix regions and the electric potential drop across the regions can be up to several kV.
My point is that the nature of the separatrix and that of the basins of attraction are somewhat separate issues.
