I think the sentence is poorly put together, but there aren't any lies. Clojure syntax is by far more simple (and thus easier to learn) than C-style languages or Python or Ruby. But the language is harder to jump into because it places particular emphasis on programming principles that are confusing to new programmers, like function purity, recursion and higher-order functions. Keep in mind too that different Lisps have different syntax. The only thing in common between them is Polish notation, S-expressions and a macro system. A Clojure program and a Common Lisp program look and feel very different.
