(seq? ...) tests for whether or not the argument is a sequence, i.e. an instance of ISeq.
(seq ...) works on things that are "seq-able", basically any kind of collection (instances of IPersistantCollection, instances of java.util.Collection, Strings, Arrays, etc.), not solely instances of ISeq. If you look at their docs, they all say they accept a collection, not a sequence. So, the String "abc" is seq-able, but it is not a sequence itself. HTH, - J.
