If a line has loss, the SWR varies along the line, being the greatest at
the load and decreasing toward the source. (The concept of SWR at a
single point is well understood and widely used and accepted, even
though it deviates from the original literal definition.) In that case,
the meter will correctly read the SWR at the position where it's placed.
That position can be anywhere along the line including either end.

.... and for most practical purposes, with knowledge of the matched
line loss, the VSWR at any other point on that line can be estimated
with reasonable accuracy from the measurement at a point on the line.
