Hello teor,
teor:
If you don't specify OutboundBindAddressOR [IPv6], any IPv6 connections a relay makes will go via the OS routing table, which may use the same address as OutboundBindAddressExit.
Thank you for this input, I added an OutboundBindAddress line (without "OR") for IPv6 as well (IPv6 ORPort line is already in place).

Also, the documentation is unclear, and we need to fix it: https://trac.torproject.org/projects/tor/ticket/22145
That was me filing that ticket.
thanks, nusenu
