I think this is just a problem on the part of the reader. Some readers 
want to have explanations laid out a certain way that is easier for them 
to follow. If the writer does not follow that way, then the reader will 
sometimes go into a snit, saying that they could not follow what was 
being done because it wasn't presented in the desired way. This does not 
make the author's explanation a trick or a stunt.

Mathematics is just a toolbox and a language. When physicists use 
mathematics, they fully expect the reader to be FLUENT with it, not just 
passable.
