Title tag discrepancy - is this a Yoast or SEOMoz thing?

[vernonmack]

Just took on a WP site using Yoast - need help understanding the title tag.  SEOMoz reports that the HP title tag is 159 characters, but there are only 60 characters entered in the plug-in field and GWT reports no "too long" title tags.  Is this a Yoast thing?

• Wordpress: San Diego Plumbing, Heating and Air Conditioning Specialists (60)
• Google Webmaster Tools – reporting 0 titles too long
• SEO Moz: San Diego Plumbing, Heating and Air Conditioning Specialists | Anderson Plumbing Heating and Air » San Diego Plumbing, Heating and Air Conditioning Specialists (159)

The ones saying it's long are including the site name. So in the WP plug-in, you're only typing in your title -- Best Blog Post Ever -- but how it's displayed is -- Best Blog Post Ever | Example.com -- and that's what the SEOmoz tool is picking up as your entire title tag.
