I don't have any clue about luatex, but most likely the texbook is still
normative here:

"In general, '\parshape=n i1 l1 i2 l2 ... in ln' specifies a paragraph
whose first n lines will have lengths l1, l2, ..., ln, respectively and
they will be indented from the left margin by the respective amounts i1,
i2, ..., in.
