Hi, Stefan.

The staves do not start on the first beat, but a tiny bit before - since 
you have the grace note in "notiert". Thus, the second instrumentName 
change is considered /after/ the beginnings of the staves are drawn, and 
does not affect this line. (The instrumentName property is evaluated 
when the staff gets initialized.)
Alignment with grace notes is a common problem, e.g. there's a bunch of 
snippets about proper grace notes just before or after special bar 
lines. The quintessence: Always use a grace skip of the same length in 
all other voices, if something strange happens, and chances are that 
everything is fine again.

Two possible solutions here:
Either change
  ausfuehr = \relative c'' {
    \grace s8
    c4(->\> b\!) c4 r4 \bar"||"
  }
to start on the same beat, or use
  \new Staff \with { instrumentName = "..." } { ... }
to change the default for this Staff instance.


Cheers,
Alexander
