Rather: Mathematicians were able to develop an axiomatic framework in which these transformations have a well-defined meaning.

Potato, potahto. If the experiment produced different results, mathematicians would not be asked for an opinion until the physicists came up with some other math. Because the experiment matched, mathematicians were obliged to invent a framework to justify it.
