When writing a single comment on a line this line is correctly ignored.
When writing two comments on a single line this line is not ignored but interpreted as a blank line.
See this page for an example that illustrates the issue:

It's not a big problem and there should be only few cases when one actually writes two separate comments on a single line, however formatting shouldn't change depending on if there are only one or two comments on the line.
