Could be a version thing, yeah. Here's what I'm working with:

dan@framework:~/rsync$ rsync --version
rsync  version 3.2.7  protocol version 32
[...more stuff...]


For ref, did the exact commands you posted, just in case my previous
test somehow handled the backup-dir because I did rsync without delete
first.

dan@framework:~/rsync$ mkdir 1temp 2temp
dan@framework:~/rsync$ touch 1temp/test
dan@framework:~/rsync$ touch 2temp/extratest

  (NB: edited command to deal with line-wrapping)

dan@framework:~/rsync$ rsync -av --backup-dir=elsewhere --delete \
                        1temp/ 2temp/
sending incremental file list
deleting extratest
./
test

sent 116 bytes  received 51 bytes  334.00 bytes/sec

dan@framework:~/rsync$ ls -al 1temp/*

dan@framework:~/rsync$ ls -al 2temp/*

There might also be the issue that the testing is using zero-byte files,
that has caused me heartache in the past.

Realistically though, as I understand your actual situation, this series
of commands is closer to what happened, right?

(1) Created some new source directory (and files), then ran rsync
dan@framework:~/rsync$ mkdir -p src/oops dest
dan@framework:~/rsync$ touch src/oops/somefile.txt
dan@framework:~/rsync$ rsync -av src/ dest
sending incremental file list
oops/
oops/somefile.txt

sent 157 bytes  received 39 bytes  392.00 bytes/sec
total size is 0  speedup is 0.00

(2) Realized there was a mistake, corrected the source tree...
dan@framework:~/rsync$ mkdir src/correct
dan@framework:~/rsync$ mv src/oops/somefile.txt src/correct/somefile.txt
dan@framework:~/rsync$ rmdir src/oops


(3)need to re-sync with the destination, and cleanup the wrong files.
Dry-run to make sure stuff we expect to happen will happen... 

  (NB: edited the command to deal with line-wrapping)

dan@framework:~/rsync$ rsync -av --backup-dir=backupdir --delete \
                        --dry-run src/ dest
sending incremental file list
deleting oops/somefile.txt
deleting oops/
./
correct/
correct/somefile.txt

sent 130 bytes  received 56 bytes  372.00 bytes/sec
total size is 0  speedup is 0.00 (DRY RUN)

(4) dry-run looked good, so run without that switch.

  (NB: Edited the command to deal with line-wrapping)

dan@framework:~/rsync$ rsync -av --backup-dir=backupdir --delete \
                         src/ dest
sending incremental file list
deleting oops/somefile.txt
deleting oops/
./
correct/
correct/somefile.txt

sent 170 bytes  received 76 bytes  492.00 bytes/sec
total size is 0  speedup is 0.00

(5) checked the result
dan@framework:~/rsync$ ls -al src
total 12
drwxr-xr-x 3 dan dan 4096 Oct 21 15:42 .
drwxr-xr-x 4 dan dan 4096 Oct 21 15:42 ..
drwxr-xr-x 2 dan dan 4096 Oct 21 15:42 correct
dan@framework:~/rsync$ ls -al dest/
total 16
drwxr-xr-x 4 dan dan 4096 Oct 21 15:42 .
drwxr-xr-x 4 dan dan 4096 Oct 21 15:42 ..
drwxr-xr-x 3 dan dan 4096 Oct 21 15:43 backupdir
drwxr-xr-x 2 dan dan 4096 Oct 21 15:42 correct
