Hello,

This is a pathological regexp. [^%] is anything but a percent sign, so
it can contain newline characters. Basically [^%]* can match an entire
buffer if it doesn't contain any %.

I think the regexp used in `reftex-using-biblatex-p' should be

  "^[^%\n]*\\\\usepackage.*{biblatex}"


Regards,
