Yes Very likely he would not be able to connect.

That is not how WPA-PSK works, or put another way any AP that did what you
just wrote would not pass WiFi interoperability testing. The AP and the STA
(in this case the laptop) send information elements to each other stating
what level of encryption that they support and they agree on the highest
level of security that they both support, in this case that would be TKIP.
By the way, AES is not tested for interoperability in WPA; just in WPA2.

The implementations in most WPA (versus WPA2) residential routers
seems to be that the AES setting is exclusive and AES only. I've also
suspected that only the TKIP setting is tested even if an AES setting
is present on the device.
