Given the following sketch:

1. Selecting the two vertical lines and specifying a distance results in a constraints error.
2. Selecting the two points at the bottom of those lines and specifying a distance results in moving the left vertical line to the desired location AND keeps it parallel to the one on the right.

To put it another way, the thing I can’t do by selecting lines, I can do by selecting points, even though the result is/should be exactly the same.
