In my mind it's a cleaner separation to do it with multiple files. The
page(s) responsible for the "content" can focus exclusively on that content,
and the page responsible for laying out the template (i.e. putting the named
"content" elements in place) can focus on that. It ends up being very easy
to maintain this way. This is especially true in the case where your
template defines multiple "non-direct" named "content" elements. In my
example you can develop these elements of content as reusable components...

To be honest, I had never even given your suggestion any thought. I imagine
there may be situations where this would be extremely convenient, and as
long as it works I'd say do it if it fits your needs...
