Yes it is. There are posts on here almost everyday about someone buying a used Mac and having Lion or Mt Lion installed on it and those new owners not being able to update the systems or do a clean reinstall because the system original came with Snow Leopard, and now has Lion or Mt Lion installed, or came with Lion and now has Mt Lion installed.
The problem isn't as bad if the system originally came with Lion as that is always available from the Online Internet Recovery system. But if it came with Snow Leopard originally and the seller didn't included the original system discs the new owner has to order a replacement set from Apple.
It get even more confusing with Mavericks. Even though Mavericks is a free upgrade from either Snow Leopard, Lion or Mt Lion it is still tied to one persons Apple ID and can not be transferred to another person. So if you have a Mac that originally came with Snow Leopard, Lion or Mt Lion and you installed Mavericks and now wanted to sell it you have to reinstall the Original version of OS X that came on it when it was new. Otherwise the version of OS X that is now installed, Mavericks, ( even though Mavericks is totally free to everyone) is TIED to that persons Apple ID.

OK, I will try again - I'm in the UK and have fast broadband - and I will call Apple support again. I don't want to sell it if it isn't right. But, if this is a widespread problem then presumably hundreds or thousands of Macs are being sold with the same problem, no?
I'm not even sure if it is a problem - if I download MT LION then the new user enters their name, ID etc. then they will have total access to that machine, surely not? No trace of my ID will exist, right, even though LION and MT LION was once connected to me?
