I don't think there is any documentation that describes uBlas mechanism
itself and if you want to really see how it works I would suggest to try
following the execution using a debugger.

Before that though you will need to know about the programming idiom
uBlas is using known as "Expression templates". This techniques is used
to build the algebraic expression tree at COMPILE time and hence allow
for avoidance of temporaries amongst other things. There are a few
things online but the very best resource I know that describes
expression templates (with a very clean linear algebra implementation )
is " C++ Templates - The Complete Guide" by David Vandevoorde and
Nicolai M. Josuttis ( Chapter 18)

Additionally the Wikipedia entry has an implementation of a sort
Expression templates mechanism that is actually based on uBlas and I
also find it an excellent read:

To understand how all those work you may need to consult some of those
resources and most importantly make a small implementation of your own -
which is not terribly difficult once you get the underlying principles.
