I'm going to go out on a limb here, without consulting the source

vertices in exactly the same order starting at exactly the same point
are counted. The equals() function is allowing for differences in
start point, direction and inconsequential vertices.
YMMV.

Hi Rhys/Paul,
I think that the '=' is specified by the B-Tree operator class, in which
case according to the source, equality appears to be specified simply by
bounding box equality.
ATB,
Mark.
