Maybe.

Markus does a lot of what most (or perhaps some) consider thoughtless.

A generic point might be maximizing the local scope of declarations.

Maximizing the local scope can make reading easier as the type of an
automatic used for a temporary purpose can be found closer to the code
that uses it.  This is especially true for long line-count functions.

IMO: it's a reasonable goal though in this instance perhaps unnecessary.
