Sort of yes. He would take the same tattoo texture and rotate it to fit in the different poses. Currently there are 6 poses. Standing, hands and knees, doggy, missionary, leaning back, and prone blowjob. Looks like he is adding a few more poses in the upcoming updates.
Takes time, but not really as much as a "render time" issue like daz things. The characters are more like paper dolls with plug in pieces that are animated.
Here are all the files that apply to Jean in the standing position right now for example
