I cannot set a static IPv6 address to an interface previously configured with IPv4 using pipework

Static IPv6 configuration doesn't work:
sudo pipework br4 -i eth1 634f98b6dafd 2001:db8:44::1/64@2001:db8:44::100

But the interface is capable of aquiring an IPv6 (through SLAAC) and an IPv6 gateway as soon as the bridge br4 it is connected to a router

It is worth mentioning that it is the same the other way around:
If I create a new interface and 1st assign an IPv6 address and gateway to it, I cannot add to it an IPv4 address:
