Oh, and also...

A response I gave on this very issue from the post you quoted:

"...With the second case, again, even if iptables accept 'in' and 'out' 
as values, because the patches I submitted yesterday allow for backwards 
compatibility, the kernel would be able to process these matches without 
any issues.

If you look at the code, the iptables code is raising both DIM_TWO_SRC 
as well as the new DIM_IFACE bits in the 'flags' variable. The set 
matching functions of the "old" kernel will "know" of and take into 
account just the DIM_TWO_SRC bit to produce a match, which is quite fine 
and it is how is supposed to work in the first place, so again, a match 
will be produced and I don't see any issues here either."

If you know any different I am all eyes/ears etc!
