After a hard reset all user profiles are now accessible by every user

I initially had our office time capsule set up with 3 seperate user accounts ("profiles") viathese instructions. Thus each user had a login for the time capsule that would then show them a shared folder that all users could see, and then a personal folder that only those logged into that account could see and access.

While I was out of the office a co-worker was having trouble connecting his new iMac to the time capsule, so he called apple for assistance and they had him do a hard reset. The hard reset saved all the profiles and all information in each folder, but now everyone can access every folder. I'm not completely sure of what steps they took to set it up after the hard reset, but now, no matter which account you are logged in as you see:

-"Shared"

-(Shared folder)

-"Users"

-(user 1)

-(user 2)

-(user 3)

So you have complete access to each users folders. Does anyone know if there is any easier way to set the user profiles back up the way they were originally set up by myself, or do I basically have to re-do the whole process (which includes saving and transfering all folders--which is a long process)?
