I tried to figure it out, but after reading the code, I got the
impression that it is intended to work.

I guess both are ok and no one cares. Most people seem to prefer the
lowercase version. C-h M just tries to be cool.
Some background: we have `major-mode', which is bound to a symbol naming
the mode, and the pretty version `mode-name' which specifies a string
(most of the time) to be displayed in the mode-line. See the macro
`define-derived-mode' for example, where you specify both kinds of
names.
