independent vlan learning

HI guys, about this of wiki.

Vlan tag id based forwarding takes into account the MAC addresses dynamically learned or manually added in the host table. QCA8337 and AR8327 switch-chips also support Independent VLAN learning (IVL) which does the learning based on both MAC addresses and VLAN IDs thus allowing the same MAC to be used in multiple VLANs. The option “independent-learning” in VLAN table entries enables this feature.

someone could explain a little more about IVL or raise usage examples?

thanks for help.
