Okay, let's try.

\documentclass{article}
\usepackage{fontspec}
\begin{document}
\long\def\1{%
  \fontspec{TeX Gyre Pagella}
  \csname f at family\endcsname\par
  \fontspec[Numbers=OldStyle]{TeX Gyre Pagella}
  \csname f at family\endcsname\par
}
\1
\end{document}

Taking a look in the log file produces:
  " 3696 words of font info for 21 fonts, out of 3000000 for 5000"

Now try

\documentclass{article}
\usepackage{fontspec}
\begin{document}
\long\def\1{%
  \fontspec{TeX Gyre Pagella}
  \csname f at family\endcsname\par
  \fontspec[Numbers=OldStyle]{TeX Gyre Pagella}
  \csname f at family\endcsname\par
}
\def\2{\1\1\1\1\1\1\1\1\1\1}
\def\3{\2\2\2\2\2\2\2\2\2\2}
\3\3\3
\end{document}

Which gives:
  " 3696 words of font info for 21 fonts, out of 3000000 for 5000"

Where's the problem?
Is this example the kind of situation you were talking about?
