I don't think you are missing anything.

A PSK authentication is simply that. TKIP and AES are encryption
methods. Different brands of wireless routers and access points differ
in their methods for choosing the security method. For example, my
WRT54G uses WPA Personal and WPA Enterprise terminology which only helps
to confuse things because they are using the differentiation to signify
authentication methods. 'Personal' means PSK and 'Enterprise' means
Radius server.
