After calls to

That's because it creates a local binding for this variable before detecting the tool. In order not to interfere with its other uses.

Only after I do M-: semantic-symref-detect-symref-tool, the value of
semantic-symref-tool changes to 'global (because I have GPATH file
generated in rootdir).

So global is not used at all by xref-find-references.

Try M-x debug-on-entry, maybe.

It was my mistake earlier; semantic/symref IS required. But
semantic-symref-detect-symref-tool doesn't seem be called at all because
the semantic-symref-tool value stays at 'detect unless I call
semantic-symref-detect-symref-tool manually.

Can you confirm the above?

Nope!
