Kinematic profiles at 12 Gyr of three simulations with prograde rotation (with respect to the orbital angular momentum) compared to their retrograde counterparts. For the retrograde profiles, we plot the absolute values. Each profile has been normalized by its corresponding Jacobi radius, r_j. Retrograde GCs are indicated as solid lines, while prograde ones are shown as dotted lines. Although prograde and retrograde simulations pairs have identical initial structures and rotation strengths, they significantly differ after 12 Gyr of evolution due to the complex coupling of internal rotation and the tidal field. Retrograde GCs retain a higher amount of angular momentum and show significant differences in rotation both in their outskirts and in the intermediate regions (∼0.5 r_j).
