Not sure what you're asking here. It wouldn't work to reset
\ProcessingResult to \l_xparse_arg_toks only at the beginning of
parsing the arguments of the command, as any processor can redefine it
as a macro and then another can come along that expects it to be a toks
register again; it would have to be reset before each processor.
