Indeed, and FWIW, that logic is documented here:

MSYS paths are not only those of the form "/c/foo". For example:
"/home/dani/foo", "/usr/local" and, in general any UNIX-like path are
valid MSYS paths.
And moreover, any MSYS path could be mounted to any Windows-native
path (type "mount" to see the current mapping).
Therefore, it is clear that supporting MSYS/Cygwin paths from the
MS-Windows port of Emacs is far more complex that simply translating
"/C" into "C:".
