The only rear recovery point that I am familiar with, on the R50 is using a hitch.
I don't know much (if anything!) about the points you are talking about, but be careful, as often points like that are only for tiedown purposes, and wont hold for recovery. Hopefully someone who knows more about them can chime in, and let you know more about them.
Before I had the bumper made, I had a hitch, as mentioned it does add some clearance issues, but I used to hit mine off of things all the time... It took it all in stride!
