A correct statement might be that "John Rohner uses magnetic confinement to keep the helium located axially at the center of the cylinder."
The majority of the time there is no magnetic confinement. The only reason helium _might_ remain at the center of the cylinder is that, being of lower molecular weight, it is more easily driven to the center during the brief periods of axial confinement and, once there, the deionized state helium atoms will have to diffuse outward toward the edges. However, even this hope is unlikely to be true since during the compression stroke the helium gas is undergoing turbulence and therefore is likely highly mixed with the consequent migration to the edges of the cylinder.
