When IPR for a given singular vector is O(1) rather than O(1 / sqrt(n)), this can indicate that the singular vector is localizing on a small subset of nodes. Oftentimes this localization indicates overfitting. If you see IPR values that are not close to zero (where "close to zero" is something you sort of have to pick up over time), then you need to some further investigation to see if you have localization and that localization corresponds to overfitting. Note, however, that not all localization is overfitting.
