I have yet to find a difference between these two in terms of the end result.
The only difference I have detected so far is that when you combine docs and
the reviewing pane is open, it shows the changes with the authors and their
respective colours.

Lorrie:
Comparing two documents forces you to accept all tracked changes in
both documents before you compare the documents and, as you've already
noticed, by default does not display the reviewer's name. Hence it is
best suited to process tracked changes from the author and a single
reviewer (or simply to compare two different versions of the same
document prepared by the author).
Combining two documents preserves the tracked changes in each document
and by default displays the name of each reviewer. You can then save
the combined document, close it, set it as the Original document and
combine it with still another Revised document (and so on). All
tracked changes will be identified with the respective reviewer. Hence
it is well suited to processing changes from the author and 2 or more
reviewers.
The Label changes with box can be used to supply or override
reviewers' names (with some limitations).
