Okay, let me try to rephrase it:

Suppose you open a large, 100 KiB or so, HTML page and scroll down
several pages. Your screen now displays formatted lines 1000-1024
and your cursor is on line 1020 on a hyperlink.

My suggestion would be that on '\' lynx now tries to find the line
number of the source line which is responsible for the line 1000
of the formatted view, and then starts displaying from there.

The only issue with that might be that between (formatted) 1000 and
(formatted) 1020 - the hyperlink/cursor line - are only 20 lines,
but in the HTML view might be several 100 (think of embedded JS).
But it's better than a non-determined behaviour, and you could
document that on toggling views the "top corner of the screen"
(formatted line 1000, in my example) stays the same.

No, just changing it (so it works).
