Does Word do this when applying Styles to a paragraph a second time?

[Bobosmite]

When I apply a Style to a paragraph, it seems to only apply only the Paragraph settings...justification, indent, etc. When I click a second time, it seems to then apply the Font settings...italics, size, etc. I see this happening in document I'm working on and need to know if that's the way Word works or if it's just "one of those things". If Word is meant to work like this, it could be very useful when applying Styles to keep the italic words from turning to normal.
