Marco,

This is not a bug in the program, but a misunderstanding of how 
overrides work.

\override applies to *everything* that happens in that musical moment, 
regardless of which Voice it is defined in.  So what happens is not that
the tie in the first voice is deleted; it's just placed at the same location
as the tie in the second voice, since it has the same control points.

This is a case where you would like to use \tweak, instead of \override.
However, since the tie is not directly connected to the input, (it's generated
automatically), I don't think you can use \tweak.  The tweak gets applied to
the chord, not the tie.

I think that you will need to create a music function to tweak only one tie
from a chord.  

Please see the Learning Manual for version 2.11, section 4.1.4 Tweaking 
commands, for an explanation of why and how to use \tweak vs. \override.

Thanks,

Carl
