It talks about "in the middle of a sequence .. that ... is invisible"

    Emacs cannot display the cursor when point is in the middle of a
    sequence of text that has the ‘display’ or ‘composition’ property, or is
    invisible.  Therefore, after a command finishes and returns to the
    command loop, if point is within such a sequence, the command loop
    normally moves point to the edge of the sequence, making this sequence
    effectively intangible.

The situation I encountered is when point ends up not in the middle, but
already on the edge. So, Emacs moving point to _other_ edge was
surprising.
