That's right.  Another way to solve this is to use neither old- nor
new-style and simply use explicit symbol names.  I.e. add backslash
before each comma and backquote:

   (` ...)   -->  (\` ...)
   (, ...)   -->  (\, ...)
   (,@ ...)  -->  (\,@ ...)

Actually, while commas are usually only used within backquotes, the `
and , special syntax can also be used for other things than the
backquote macro.
