Zhai -

I'm having a difficult time trying to figure out what problem this
solves and how it is proposed to be employed.

Of the current proposed MPLS apps for BFD there's VCCV and LSP-Ping
initiated BFD sessions.  In both cases the FEC binding is established
before the BFD session comes up.  You have Source and Destination IP
addresses as well as the pair of discriminators.  This is sufficient to
ensure that any BFD packet you might accidentally intercept is unique.
So what extra value comes from the filter???
