Where do you get that idea?
Do you think there is a discrepancy between the mathematical
tranformation and the way the transformation is represented
in a spacetime diagram?

I don't say there is a purely mathematical discrepancy. I do
say that the 4D spacetime geometry goes far beyond what the
original transformation equations actually say. They refer only
to time dilation and foreshortening.

You clearly have no idea what you are talking about.
This sounds familiar however, and so does your name.
Did some research...

Ah well...
Apparently nothing has changed.

They say nothing about
how this actually happens, and say nothing about something
like a 4D spacetime geometry. That is an interpretation imposed
on the equations. From a conceptual perspective, as
representing an underlying reality, as distinct from being
a purely mathematical representation, the 4D geometry
doesn't make sense.
