CM Super is not a default, CM (Computer Modern) is the default. To  
ease our life to make TeX output readable CM Super was created.

It's none of them yet, so there is no need to know whether it's this  
or that substitute.

\usepackage{lmodern} switches in LaTeX to Latin Modern. Similiar  
statements switch to other TrueType or PostScript fonts. Loading no  
foreign font makes you use CM (Computer Modern). Once the CM-Super  
fonts are installed the MAP files are changed so that pdfTeX, dvips,  
(x)dvipdfm(x) use CM-Super instead of CM.

These come from the "\usepackage{lmodern}" statement.

There can usually be only one default CM. CM-Super is an add-on.

Not loading any other font, so it's rather a non-declaration that  
assures the use of CM.
