I am not sure I understand.  The idea in bibtex-autokey-transcriptions
is that each match of OLD-REGEXP is replaced in full by NEW-STRING.
Subexpressions are ignored.

In LaTeX syntax, OLD-REGEXP can appear anywhere inside what LaTeX
considers a word (which even may include spaces).  So to make things
more fool-proofed, it would be necessary to parse more carefully the
LaTeX code.  I do not think this effort is needed here as these
regexps have worked well for at least two decades.  The patch fixes
a minor problem of these regexps pointed out by the OP.  But
otherwise it preserves their spirit.
