Was there a change in behavior with regards to the interaction between

To be more precise... The following command using 6.1.2 generates output
with 2 video streams; one for the original (1920x1080) and one for the
scaled (1280x720):

Thanks... that helps, but it doesn't really explain why it's different in
4.4.2. Was this a bug that was fixed? Or was the behavior intentionally
changed?
I'm mostly curious more than anything. I have a perl script that relied
on the 4.4.2 behavior and I'm pondering the best way to fix it to support
ffmpeg > 6.1.2.
