[Samba] Profile Location Best Practice

[Server Gremlin]

I have a question about using roaming profiles in a Samba PDC controlled 
domain.  I know that with Windows 95 and that generation or so, the 
profile had to be stored in the same directory as the home folder.  
("/sambahomes/john/profile" for example.)  You didn't have a choice 
because of technical reasons.  But that restriction no longer applies 
with modern versions of Windows, and it seems like the convention has 
shifted to that of storing profiles in one place 
(/sambaprofiles/john/profile) while storing home directories in another 
(/sambahomes/john).

What is the advantage of this setup, if any?

Thanks,
