Yes, that very sentence says that :-). Read it like this:

"A put or accumulate must not access a target window once a load/store update -- or a put or accumulate update to another overlapping target window -- has started on a location in the target window, until the update becomes visible in the public copy of the window.    ..... the restriction applies to operations even if they access disjoint locations in the window."
