The bug should be the same in both examples, though I do see I transposed a '+' into an '*'. That wasn't intentional; the two are supposed to form the same AST, but with purposeful alignment in the second making bugs in both far more visible. (You seem to be using "alignment of characters" to mean "alignment with indentation", which is more limiting than I would take "Aligning a character on one line with an arbitrary character on another line" to be.)
