I think the reason would likely be that the font-locking displays
exponents with a smaller font, and this includes the spaces used for
indentation.

Of course, after cut&paste the difference disappears.  Tricky.  It is
probably the sanest course to stop the exponent/subscript treatment
completely (or switch it to just different colors instead of
size/position changes) as soon as a single newline is part of the
construct.
