I can believe you but this is not mention in E-02.
Here is the section where I saw this:
2.7.3 Only one current path shall be provided from
each anode to the cathodic bonding system.
1. Sacrificial anodes may be mounted directly on
the metal to be protected.
2. Zinc galvanic anodes may be applied directly to
aluminum, steel and non-metallic hulls without shielding.
3. Better current distribution will be obtained with
a dielectric shield between the anodes and metals to be
protected providing the anode is electrically connected to
the metal being protected.
2.7.4 Magnesium anodes shall not be directly
coupled to the surface to be protected without dielectric
