Reciprocol Limitations or Counter Limitations are the reverse idea of a Reciprocal Enhancements (ie Counter Enhancements).
Instead of designing an enhancement based on removing a limitation (for example Not Divided Magery or perhaps call it Undivided Magery enhancement to cancel out the Divided Magery limitation) it would be a limitation based on removing an enhancement.
For example if Variable was built into an ability then Not Variable would be its reciprocal limitation.
This might be useful if for example, designing Temporary Enhancements for the ability which were Limited Enhancements.
This relates to Temporary Disadvantage, Shutdown, essentially instead of adding a disadvantage, you remove an advantage.
But in this case with modifiers instead of underlying traits: instead of adding a limitation, you remove an enhancement.
