It's not creating a style, the option will show you styles along with the
direct formatting. IOW, what is actually in your document/template.

So
for example if you bold a word in a paragraph that uses the Body Text style
the format is actually Body Text + Bold.
You can tell the difference if you look to the right of the style name those
that appear as a result of direct formatting won't have the style indicator
(¶, a, or ¶a, ) next to it.
Ideally, the direct formatting should be replaced with a style, for example
instead of Bold use the Strong character style, but if you click the Options
link at the bottom of the task pane you'll see a section for "Select
formatting to show as styles". If you turn off the options listed then
you'll only see Styles in the task pane.
