In the code src/finiteVolume/fvMesh/wallDist/patchDistMethods/Poisson/PoissonPatchDistMethod.C it twice does clipping:

    // For overset: enforce smooth y field (yPsi is smooth, magGradyPsi is
    // not)
    mesh_.interpolate(y);

    // Need to stabilise the y for overset meshes since the holed cells
    // keep the initial value (0.0) so the gradient of that will be
    // zero as well. Turbulence models do not like zero wall distance.
    y.max(SMALL);

    // For overset: enforce smooth y field (yPsi is smooth, magGradyPsi is
    // not)
    mesh_.interpolate(y);

Not sure but only second one probably needs to be done. Check.
