I think it’s simply that OP follows him, he tweets a lot, and OP is a Lemmy power user so posts his tweets here frequently. Any time I see his tweets it’s always been posted by OP; I’ve seen some users suspect OP of being a bot but given the amount of regular comments they also post I feel like it might just be someone who has a pretty regular routine of posting stuff they’ve found during the day.

All just speculation from me though…
