If you want the logo to appear in one place on title slides and another place on the rest of your slides, position it in one place on the title master and in a different place on the slide master.
Your organization might have a graphics file, such as a logo, for you to include in presentations. You can insert that wherever you want it, on the slide master or title master or both.
When you insert the logo on the slide master, it will appear on every slide except for those with a Title Slide layout. (Exception: If you insert the picture on a slide master before a title master is inserted, the picture appears on title slides, too. To keep the picture off title slides, you'd insert the title master and delete the picture from there.)
If you insert the logo on just the title master, it will appear only on the title master.
