It will _not_ interfere.  The main reason to avoid multiple instances
here is performance: every occurence of \context { \Staff ... } copies
the currently active Staff context definition, adds material to it, then
takes the result, looks up its \name in the definition, gets the
respective context definition in the output definition (\layout) and
replaces it with the modified copy.  Not doing this over and over is a
bit of courtesy towards LilyPond, even though there are probably other
things slowing it down even more.
