Update not working with multiple paths specified in hgrc

Hi,

In the project i work for, we have developers working both on linux and windows environment.
The repository created on linux is accessible on windows using a harmonized network drive.
I was wondering if there was any way of executing all mercurial commands on this mercurial repository shared between windows and linux platforms.
Here is the scenario:
I have a directory in linux say /home/xyz which is accessible on windows platform on a mapped network drive Z:\
I clone a repository test from /home/xyz/test_orig into /home/xyz. This repository automatically becomes accessible on windows platform as Z:\test
The .hg/hgrc file will contain the path from where i cloned this repository (/home/xyz/test_orig) as an entry

[path]
default = /home/xyz/test_orig

This means that any push/pull i perform from unix environment will push/pull changes to/from the repo specified in the default path.
However, the same command if issued on Windows platform fails stating that /home/xyz/test_orig is not accessible
Now i tweaked the hgrc file a bit to add another entry for windows
My hgrc file for the repository test now looks like the following

[path]
default = Z:\test_orig
default1 = /home/xyz/test_orig

Push/pull and update works seamlessly on windows platform now.

Now there is another repository say test2 at /home/xyz/test2 which is again cloned from /home/xyz/test_orig
The hgrc file for this repository is identical to that of the repository test

[path]
default = Z:\test_orig
default1 = /home/xyz/test_orig

On linux platform, i was able to pull  changes from test_orig by using the command
hg pull default1
However on executing the update command it failed giving the error :

hg update
pulling subrepo abc from /home/xyz/test2/Z:\test_orig/abc
abort: repository /home/xyz/test2/Z:\test_orig/abc not found!

On searching, i found that having multiple paths is supported in mercurial so as to have push and pull to separate repositories.
Is this feature full fledged so that it supports update and other mercurial commands too?

I kind of stuck here and this is a bit critical. It would be great if someone could respond to this mail ASAP and guide me.

Thanks and Regards,
