It seems "Eye" or maya represents a traditional barrier between an aspirant an one's "future" self (or, transcending-including space-time barrier).
Of course. But Art/Sagittarius represents the
aspiration to reach Tiphereth, which is more important than knowing about the egoic illusions that blind us to Tipheric reality. Its energy is essential to the process of piercing those illusions, hence its position on the standard Tree. However, the traditional arrangement also has the path of Ayin/Devil going into Tiphereth, so it isn't excluded. The creator of the site to which you linked seems not to understand that too clearly. What he doesn't understand, he replaces.
What confuses me most about it is its constant references to physics. I wouldn't study the Upanishads to discover parallels with genetics, nor the Gospel of St. Thomas to learn about principles of inorganic chemistry. And I wouldn't closely equate the Tree of Life, in a revised form or the traditional one, with the laws of physics. Sure, there will be occasional parallels, and the Tetractys material is kinda fun. But that doesn't mean it's of any help in the process of
inner transformation. Whereas, the Tree we have is a proven tool for that.
Which, to my mind, is the best argument against not opting for superficially more "logical" arrangements. There are lots of mathematical relationships among the Tree and its components, but you could say that about the human skeleton. That doesn't mean our physical existence is for establishing a point about mathematics.
