Morphology
The image of a 'line drawn on water' evokes an immediately obvious literal impossibility — a line on water would not hold and would quickly disappear — so the metaphor of impermanence or unreliability is directly derivable from the constituent words. This simple, grounded metaphor is cross-linguistically natural and therefore a B1 learner who knows the constituent meanings can reasonably infer the idiomatic sense.
Etymology
Line drawn on water comes from the simple image of drawing a line on water, which disappears at once. So it means 'not lasting' or 'not to be trusted'.
