I cannot image how two same mass orbits would look like? ....would
they propagate forward or remain in one constant region?

One location, which doesn't seem to make sense, says: "Since stars
have about the same mass (within a factor of 20), they both orbit
around a common point, called the center of mass, that is
significantly different from one of the star's center.".

(http://www.astronomynotes.com/starprop/s10.htm)

Two bodies, whether the same mass or not, rotate around
the common center of mass.

If one is much heaver than the other, that center of mass
is approximately the center of the heavier body.
