In three-line mode in the document, the script aligns to the right.
I thought to myself that it would be great if in such a situation the script would apply a two-row window, i.e. another row break and tab.
This is very common in holy books and especially in Siddur
To be more exact, if a paragraph has 3 lines, Dropword III applies the indent only to the second line. It doesn’t actually modify the paragraph alignment.
What you’re suggesting is that for paragraphs with exactly 3 lines, Dropword III should apply an equal indent to lines 2 and 3.
But in fact, in such a case you could use InDesign’s special “align to here” character (Type > Insert Special Characters > Other > Align to Here), and there is no need to use Dropword for such paragraph at all?
