No, it doesn't. Try Table[pw[b, p], {b, -3, 3, 1.}, {p, -3, 3, 1.}]. Error messages and indeterminate values!

b must be >= 0. With negative b-values there are branch cuts and singularities (see doc). You can plot f.e Plot3D[pw[b, p], {b, 0, 3}, {p, -6, 6}]

I get a nice plot with PlotPoints -> Automatic Imo it's not a good idea to use ` ClippingStyle -> None` here
