I thought that dielectric materials conducted by some other mechanism, yes they insulate, but something else happens and electrons move across. This is all I remember from school and something to do with capacitors. So maybe the grease has this property. I am out my depth.
There's no question that "dielectric" means non-conductive under DC conditions. The confusion comes from the fact that a dielectric effectively conducts under AC conditions - a capacitor is transparent, if you like, to AC.
Regarding the case in point the manufacturers are extolling the virtues of it being a dielectric and hence not causing unintended short circuits. It does, however, make you wonder whether it can creep between contacts and cause problems ...apparently not.
