No Range Modifier and Range Skill Levels redundant?

[JamesG]

In UNTIL: DoF, the U-GEM-E Laser Rifle (pg 82) has the No Range Modifier advantage and +3 PSLs vs the Range Modifier. But doesn’t a power with the No Range Modifier advantage have, well, no range modifiers, rendering the PSLs superfluous?

The variant of the weapon with HUD aiming replaces the NRM advantage with the Line of Sight advantage. But LOS is also supposed to have no range modifiers, so the PSLs would have no utility for that variant either, right?

There might be situations where the Advantage wouldn't function for some reason -- damage to the weapon or a very specific Drain, for instance. In that case the RSLs -- which reflect the weapon's overall quality and suchlike -- could still come in handy.
