Correct. We do not try to make width of bars from two different commits comparable [*1*], but we do try to make them comparable within a single commit; for a commit that changes only a single path, you still have adds and removals to compare. The overall length is ideally one + or - per line if the graph fits the output width, but if that makes the graph too wide, we scale to fit in the output width. So a change with 41 lines gets only 41 +/- and does not consume full 80-column terminal.

[Footnote]

*1* This is very much on purpose; otherwise it will hurt the perceived latency of the command.
