Dotted unit names are supported at least since Delphi 2007 (maybe also 
from 2005 on), but they weren't extensively used back then (look at 
Collections.Generics for an example). Only XE2 did use it extensively 
which was also when support for default namespaces were added. With XE2 
the RTL units were put into a System namespace, the VCL units were put 
into a VCL namespace and the newly added FireMonkey units were added to 
a FMX namespace. The usage of default namespaces (System and VCL in case 
of a VCL application) allows the usage of backwards compatible single 
identifier unit names.

No directories are involved, it's just the naming.
