Actually, I don't think he's being pedantic at all. LSD binds to a wide array of proteins and receptors in the brain (including dopamine receptors) and the binding profile of this substance is most likely very different from that of LSD. Likely to be much more specific to 5HT2a, closer to psilocybin than LSD. IMO they just said "LSD-like" because it would make a nice headline.

See this diagram on wikipedia for LSD binding affinities (lower means more affinity): https://en.wikipedia.org/wiki/Lysergic_acid_diethylamide#/me...
