mod_vhosts_alias and partial domains

A question, obviously, for those in the know. Here's my mass virtual
host line relivant to the question:

VirtualDocumentRoot /home/sites/%-2.%-1/%-3.1/%-3.2/%-3/public_html

Of course, using examples:

www.example.com -> /home/sites/example.com/w/w/www/public_html
www.example.co.uk -> /home/sites/co.uk/e/x/example/public_html
www.example.com.au -> /home/sites/com.au/e/x/example/public_html

What would happen if I just did "example.com"? Will it remap to
/home/sites/example.com////public_html, aka
/home/sites/example.com/public_html?

(And yes, if need be I'll run the rewrite engine over them to sanitize
them)
