Creating Share Within A Share

Is it safe to create a share within a share? So, let’s say I have a path c:\parent1\child1. Parent1 is set up to be a share as well as child1. So, we have:
\\server\parent1
\\server\child1

I have been able to set this up, but I don’t know if MS recommends against this procedure since I was unable to find any resources about this. Windows uses this in an AD environment for the SYSVOL and NETLOGON shares where the NETLOGON share is actually a subfolder of SYSVOL. However, I am unsure whether this is a recommended procedure for file servers.

Thanks.
