I have recently been looking into the two-time theories and the implied concepts.

For me this seems slightly hard to grasp.

How can I see the basic concept in this theory in a fundamental way based on its implied interaction with normal 3+1 dimension?

I am interested specifically in how gauge symmetries that effectively reduce 2T-physics in 4+2 dimensions to 1T-physics in 3+1 dimensions without any Kaluza-Klein remnants.

In this blog post, a paper that derives by dimensional reduction well known super Yang-Mills (SYM) theories, such as N=1 SYM in 9+1 dimensions and N=4 SYM in 3+1 dimensions among other things using a SYM theory in 10+2 dimensions as a common more fundamental underlying theory.

As can be seen from looking at figure 1 of that paper

As stated below equation (3.1), if applying the method of deriving shadows of two time physics to obtain lower dimensional theories, Kaluza-Klein are avoided.
