You're correct. That's because a sealed beam already has a lens molded into the clear glass front, to put the correct pattern out on the road. Put a second Model A lens in front of that and it's "too much lens". (Kind of like putting in your contact lenses and then putting your regular correction glasses on on top of them. Too much correction. You can't see well.)

This guy is talking about putting a regular bulb in the headlight reflector without a lens and then focusing it. It should work. Remember to focus on the High beam, though. That filament is in the center of the reflector and should focus to a very strong spot beam.

Then you add the lens and it should look good, like in the Service Bulletins (but you may need to loosen the nut on the light and aim it to the correct height).
