Since he's talking about the app browser interface exclusively, and not accounting for the degrees of freedom in the applications themselves, it's hard to take the critique too seriously.

Even if it's what he was saying, the OS supports custom URL schemas for just this purpose. I used custom URLs to jump to records in our app from other places in the system. Granted, it's not a quick keystroke or an on-screen quick-launch bar, but it works.
And it requires you to build it into the app.
You can search and open different things with spotlight.
That said - I don't know if that's true, but that's how I understood him. This way it kind of makes sense to complain about linear approach. Can anyone confirm?
