I believe the reasoning is that if the VIP is a /128 it is most likely a 
secondary address and that the operator would like for the primary (permanent) 
address to be the source of outgoing packets from the router.

On the other hand if the VIP is a /64 it is most likely the only address in 
the prefix (i.e., backup routers do not have global addresses configured at 
all) and thus the above consideration does not apply.
