I think it's not quite like that. Modern insulating materials don't
degrade, but old ones did, or at least appeared to. For instance, oiled
paper had pinholes, and a discharge caused local carbonization, which
prompted more discharges and more carbonization.

Their claim is that the hipot can degrade some insulation and should
be kept to a minimum.
Conventional wisdom not supported by science.
