Betcha the fabric is stretching a bit as you're sewing. Try lightening the
presser foot pressure for the second stitching. If you're pressing before
the second stitching, try dry iron and pressing (up and down) instead of
ironing (side to side).

You also see this sort of twisting on a curved felled seam -- the issue there
is you're trying to stuff a larger seam allowance into a smaller area,
and if you make a very narrow fell (and clip the edge of the allowance
before felling), you can often get it to work. Sometimes I've had to
resort to hand basting or glue basting first.

I don't have a felling foot for one of my machines, so I use a modified
general purpose foot. The modification is that I've added a couple of
layers of self-stick teflon to the underside on the right side of
the foot only,which gives me a foot that's thicker on the right side
than the left. The left rides on the felled seam, the right on the single
thickness of fabric, which levels out the pressure across the area
being sewn.
