In fact, this sentence is linked to the difference between the ND
Proxy function in MIPv6 and the one in ND Proxies (aka RFC 4389): in
the first case, the IP source address of the NA message is the proxy's
one (i.e. the HA's one) and in the second case, the IP source address
is the proxied node's one.
I will modify the text.

OK. I will add text on this.
