Thanks Eli for explaining.

This is what I see with this example on my Emacs 28.2 (assume window width is 50):
,----
| EEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEE
| After
`----
So the text is "correctly" aligned to (- right 10) on the second line. Are you seeing something different?
The only problem I see is that when the word is broken and word-wrap is off then I get
,----
| EEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEE Af
| ter
`----
while if word wrap is on I get
,----
| EEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEE
| After
`----

I see. Do you mean that I should write a hook to update the alignment of "After" as more text is inserted before it (to calculate the alignment column taking the continuation lines into considerations)?
Or is there a way to have `align-to` be calculated from a function?
Thanks,
