The differences between the filled and open circles don't look that significant to me. One reason they mention that crowded sources might have higher Lx in previous work is that Antokhin et al. used XMM, which has poorer spatial resolution than Chandra and thus could inadvertently include X-rays from a nearby source whereas Chandra would be able to separate the two sources and thus exclude the spurious X-rays.
