A line-area is a "special" sort of block-area (4.5, 1st sentence), it does not have any border and padding. Furthermore, 4.4 defines the behaviour of block-areas and makes special comments that many of those feature don't apply to block-areas which are line-areas (for example for start/end-indent).
So, I'm not sure where you got your "2*start-indent" from, but I think you may not involve start/end-indent with line-areas. AFAIU, line-areas all extend to the edges of the parent content-rectangle in inline-progress-direction (i.e. start and end) if there's no instrusion. Does that help?
