Mean orbital–alignment evolution for satellites in the BL (top), BD (middle), and CS (bottom) samples. Curves correspond to the full sample with all the satellites (blue), satellites in hosts that underwent massive satellite infalls (Massive Accretion; red), satellites in hosts without a massive infall (No Massive Accretion; green), and the cleaned sample tracking satellite orbits up to the moment of the massive infall if any (orange). Any satellite with a maximum mass ratio with the host galaxy > 0.1 is considered a massive infall. The comparison highlights systematic differences between the subsamples and allows for assessment of the impact of massive satellites on the alignment trends.
