vFiler - Multiple Networks - same VLAN

I was wondering if I can have some advice about our exisiting vFiler configurations. 

We have the following IFGRP 

ifgrp create lacp IFGRP0 -b ip e0a e0b e0c e0d

This is then set to trunk our management and iSCSI connections

vlan create IFGRP0 123 456

We then have vFiler's each with 2 ipaddresses from a single VLAN. For exmaple, vf_TEST has 192.168.0.1 & 192.168.0.2. When this is mapped to VMware, it can see 2 paths to the LUN. 

My question is, what benefit is there for having to paths comming from the same network aggreagate? A former colleague suggested this was the correct setup, however I cant see the benefit.
