How can this be explained?

[Metalblaze]

The 59b has 8.13K and the Custom has 14.1K DC Resistance but they have their resonant peak at 6KHz both(?).

I also noticed from the tone chart that the PAF-style bridge humbuckers except the Demon have their resonant peak near 6KHz. 59b(6KHz), seth lover(5.9KHz), PGb (6.5KHz-a little off), Blues Trembucker(6KHz) and even the Custom(6KHz).

Is this related to the PAF-style sound or it doesn't have to do with it?

Re: How can this be explained?

Theie inductance and capacitance is different, hence the differing resonant Fc peaks ... the DCR of the pup has nothing to do with that. If you wind a pup with different gauge wire and different insulation thickness you can get a pup with the same Res peak Fc, but with way different DCR.
