Hi ainmert, Nice looking plants. I think they may be seperate. Starting life as two seedlings. They are definitely haageana but would suggest under Hunt's classification they maybe haageana ssp. haageana and not elegans. Your plants flowers look to have a pinkier colour, rather than a deep rose red colour of elegans. Also elegans tends to have a much more whiter appearance. This of course is what I can see only from the photo and may be somewhat different under normal light.
