It's working as spec'd.

The "true" indicates to add new lines.  Thus it adds new lines.

The "  " indicates to add a two-space indent.  Thus it adds a two-space
indent.

The "" and false say not to add indenting or new lines.  Thus your
output is the same as your input.

Since by default in XML all whitespace is preserved, you generally want
to output without adding any new whitespace.  But if you create elements
in-memory then you probably don't add padding whitespace so you want the
outputter to add the padding for you.  That's why you have that option.
