Ok. I guess that, in this case, mobility of an IP flow requests the MN to support the weak host model, right? 

May I suggest to reword the following sentence (section 3.2.1)

[if the IP layer at the mobile node shows one single interface, then the mobile node has one single IPv6 address configured at the IP layer: pref1::mn1. Otherwise, two different IPv6 addresses (pref1::if1 and pref1::if2) would be configured.]

As

[if the IP layer at the mobile node shows one single logical interface [ref to logical interface I-D], then the mobile node has one single IPv6 address configured at the IP layer: pref1::mn1. Otherwise, per interface IPv6 addresses (e.g. pref1::if1 and pref1::if2) would be configured; each address must be valid on every interfaces.]
