It's quite useful on templates, since you can use a combination of "clear" and <noinclude> to add usage notes directly to the template page. If "clear" isn't used and the notes contain an example use of the template (this tends to come up with infoboxes), the example (which is presumably "float: right") will overlap with the actual rendered template.
(This is, admittedly, a rather obscure example.)
There are plenty of less obscure ones. Here's one: http://en.wikipedia.org/wiki/Golden_ratio
At the end of the section "Aesthetic uses", the {{-}} prevents the large image hanging down into the next section, overlapping the section title line. And it doesn't produce a huge amount of excess space, either.
FWIW, it also comes in handy for WP:FPC, where you can be sure of keeping any images from the previous section from hanging over into the next section.
I would probably use it less if it wasn't for the ugly way images tend to cut off that line.
