[NTG-context] \setupcolumnsetlines does not work again

I thought I understood the mechanism, but I found another instance where \setupcolumnsetlines does not give the desired result: %%%%%%%%%%% \definecolumnset[Two][n=2] \starttext Test %\page \setupcolumnsetlines[Two][1][1][9] \startcolumnset[Two] \input knuth \stopcolumnset \setupcolumnsetlines[Two][1][1][9] \startcolumnset[Two] \input knuth \stopcolumnset \stoptext %%%%%%%%%%% This setup gives indeed a balanced first page and an unbalanced second page. But if the fourth line (\page) is uncommented, the second output page is unbalanced and the third page is balanced. So the mechanism is therefore more complicated than

only if the first columnset extends to more than one page the next \setupcolumnsetlines will work properly.

What is the extended rule? If this intended behaviour, what is the reason behind it? Sytse

The settings for the second columnset work when the first columnset goes over of two or more pages.

Thank you, now I understand the mechanism: only if the first columnset extends to more than one page, the next \setupcolumnsetlines will work properly. Is this a bug or a feature? If it is a feature, what is the idea behind it?
