Here's the (corrected version) of the post you cited:
mount -t smbfs -o "username=admin,password=admin" //192.168.1.1/share /tmp/share
In this instance, the "share" is exported by 192.168.1.1 (apparently a Windows machine). Local Samba clients can access it via the Linux "mount point" /tmp/share.
If another, different PC wanted to access the same share, they'd map to host 192.168.1.1 - not to your client.
