I was merely quoting the oracle note. I myself have never relied on order or
consecutiveness of sequence values, only their uniqueness per database
instance. this "new" behaviour is unexpected maybe..but makes sense if you
read the story behind the no segment clause and the fact that a value given
out by a sequence can never be stuffed back into the sequence object.
workaround: set deferred_segment_creation=FALSE and the "skip 1 jump" will
not happen

kind regards,
Andre
