I must admit I do not know what you mean precisely with the above sentence.

Do you mean "if the window is not *live*" or "if the *buffer* isn't shown"?

But between the moment you checked window-live-p and the moment you run
the above timer, if the buffer ends up displayed, there must have been
an operation that ran window-configuration-change-hook.

So IIUC this doc-view-goto-page shouldn't be required because the
window-configuration-change-hook should have caused an equivalent
doc-view-goto-page already.
