I do not know the reasons for Doepfer, but I know it from my diy time,
that sometimes you have no other chance for your layout, if you want to
avoid to make the pcb much larger.

The other possibility for certain layouts which would cause crossing
lines is, to add wire bridges to the pcb. But assumingly this makes a
pcb much more expensive, because wire brigdes have to be added manually.
