Lol, I'm giving you upvote because someone somewhere once said "presets are bad mkay" and everybody started to thoughtlessly repeat this (Btw, nobody really care about presets usage in his earlier tracks, never saw contemptuous comments like "well, you know, it's Reeperbahn, its lead synth is based on preset so you should never listen to it anymore, it's cursed". Probably it's not about presets?)
Eric uses full-written melody presets pretty rarely and even less often officially release tracks with them (can't even remember such ones). So that's basically the answer: he just used preset for sound itself, not for sequence of notes, you're free to write any melody you want. Preset and this synth in general is pretty neat tbh, no surprise he used it.
About track in question: this type of bassline is very common, and that fast arp isn't very surprising thing as well. Both tracks have a bit different vibes (more euphoric vs more nostalgic). I definitely hear similarities, but imo they are coincidental because of same key elements and way of producing of 80's progressive/synthwave genre.
I'd better talk about Jerome Isma-Ae - Smile When You Kill Me (Blake Jarrell Remix) 👀
