Two consecutive versions of the same event might seem stranger than parallel editing at first, but it simply privileges the temporal unity of each location. In fact, parallel editing implies simultaneity through its very opposite: sequence. It places shots one after the other, and yet we read them as occurring simultaneously.
a little too much of the horses & carriages eh? the intro dream and famous repetition/perspective game at the end are crazy tho (apparently later versions were edited to match the cuts with continuity?)
