That's what I'd heard, they're there to reduce "crosstalk"
that would corrupt data.
I recall back in my youth wire wrapping an RCA 1802 microprocessor
into a primitive computer Popular Electronics dubbed the
"COSMAC Elf" and with only a couple inches of wire wrapping cable
one could very clearly see multiple images bleeding over on
a high imput impedence oscilloscope.

I guess the relatively low output impedences of the driving
gates swamped out the crosstalk in this case but of course I was
only using a 1 MHz crystal to drive the thing at the time.

Oh that was a _long_ time ago.
