Without the final name-rev, it reads:
d87b90e4... b5dd9d20... 280242d1...
Without the --parent option, you get only d87b90e4...; the
option tells the command to additionally give you the (virtual)
parents in the simplified history on the same line as well.
Now, true parents of d87b90e4 are b5dd9d20 and 00449f99; the
former changes the path you are interested in, but the latter
does not. Which means in this history:
$ git show-branch d87b90e4 00449f99 280242d1

! [00449f99] Make git-fmt-merge-msg a builtin

the true history of a side branch forked at 280242d1 to 00449f99
is simplified away, and 00449f99 is replaced with the boundary
commit 280242d1:

Note that 280242d1 is reachable from v1.4.2-rc1~88, so the
traversal does not go beyond it (as you said --not $that).
