[sdiy] Twin diode clippers

[Andrew Simper]

In my research into diode clipping I noticed this circuit where there
are two diodes in each direction to soften the clipping, but there is
an interconnect in the centre:

I did a quick LTspice simulation using this schematic to see what the
difference is between adding this wire and having no wire and the
plots looked identical:

Does anyone know if there is some reason to add the extra wire with
real world diodes?

Cheers,
