switch-to-buffer-preserve-window-point is a variable defined in `window.el'.
Its value is nil

Documentation:
If non-nil, `switch-to-buffer' tries to preserve `window-point'.
If this is nil, `switch-to-buffer' displays the buffer at that
buffer's `point'.

So point here was at the beginning of the buffer.  But switching to this
buffer, which isn't displayed, puts point at the end of the buffer.

Surely that's not the intended result?
