At \begin{document} unicode-math setups the various math
definitions, such definitions can be quite complicated and so you no
longer can't use the commands as numbers. That's not very surprising
(actually I find it quite impressing that you can use them this way
in the preamble).
But you can use in the document numbers:
\documentclass{article}
\usepackage{unicode-math}
\setmathfont{Latin Modern Math}
\begin{document}
\[\plus \oiint \]
\setmathfont[range={"0002B, "0222F}]{XITS math}
\[\plus \oiint \]
\end{document}
(you can find the numbers in unicode-math-table.tex).
