Hello,
Tanchat. I will respond inline below for clarity, but before I do, I just want to say that I would always look at a sentence holistically before I decided it needed to fit into a particular category.

Dear Experts,
I know that "Prepositional Phrase after Comma" is a modifier. However, I'm not sure whether it modifies the closest noun or the subject.
Examples
1) X replaces Y, instead of Z [ instead of Z modifies X or Y, or it can be both --> ambiguous]
It would be rather confusing if Z commented on anything other than Y. If it was meant to apply to X, we would expect the alternative to be placed next to what it could stand in for:
X, instead of Z, replaces Y.
Tanchat
2) X replaces Y instead of Z [ instead of Z modifies Y right? ]
Yes, notice that
instead of follows the element that can be replaced.
Tanchat
3) X, instead of Z, replaces Y [ instead of Z modifies X right?]
Again, you are correct, and this looks just like the sentence I wrote earlier. Clarity is a must in SC.

4) More than fifty years after the Second World War, a number of African American soldiers were awarded, some of them posthumously, the Congressional Medal of Honor, the nation’s highest military award, in long-overdue recognition of their outstanding bravery. [Which does " in long-overdue recognition of their outstanding bravery " modify?]
The phrase at the end comments on the fact that the soldiers
were awarded something. In a shorter sentence, we would probably see,
... soldiers were awarded, in long-overdue recognition of their outstanding bravery, the Congressional Medal of Honor. Alternatively, we might see the phrase placed at the end, probably without a comma, but it would comment on the same thing:
... soldiers were awarded the Congressional Medal of Honor in long-overdue recognition of their outstanding bravery. We could even see the phrase moved to the beginning as a sort of introduction:
In long-overdue recognition of their outstanding bravery, ... soldiers were awarded the Congressional Medal of Honor. The reason the author might have chosen to place the phrase at the end in the original sentence is that
some of them posthumously is competing for the same space, and that phrase seems more logical when placed right after the soldiers were mentioned.
Perhaps this grammatical issue makes more sense now. It will be interesting to see what others have to say. Thank you for thinking to ask.
