I think the confusing part in regard to this issue is the fact that Ra talks about a genetic modification of 3D bodies to 4D bodies on earth. This is a process which might take a while and at one point must be 3D and 4D in existence on earth at the same time.
Considering that 4D must hide from 3D in order to preserve the law of confusion the question would be how this transition will really happen.
My opinion is that at certain moment when the 4D body will become available all the 3D people still existing on earth will be 3D graduated with double body (3D, 4D) in activation. Those people will probably be exempt from the law of confusion so that the genetic transformation of the body is possible. law of confusion is not useful anymore for a graduated 3D even though is still in 3D body.
In the beginning the law of confusion was applied to those with double body in activation just because they were leaving along 3D only people that are not ready to graduate and in order to preserve their veil.
