That is correct

That's... a really good point. I didn't consider that I'm calling a
tangle or detangle function on an entire file based on the
=:tangle-sync action= of a single block... which might have different
actions in another block for the same file!

I've attached a toy.org file which should explain what the desired
action would be in such a situation, and I fully agree that I will
likely need to modify the current tangle and detangle code so that the
sync direction is on a per-block basis, and not per-file.

I will work on this a bit more and submit a full patch with this in
mind.

Best,
Mehmet
