My conclusion at the time that I put the stream together (15 or so years ago!) was that there was not a clear case to be made for doing it in either order when using an interleaved acquisition. When using a sequential acq, then it is clear that you do mc first then stc. Given that a strong case could not be made for stc then mc for interleaved and that stc then mc is definitely wrong for sequential, I opted to go with mc then stc. I don't remember testing for differences when the order is changed.
