The How to meet WCAG2.0 states H33 as a sufficient technique for SC 2.4.4 - link purpose.
"4. Providing a supplemental description of the purpose of a link using one of the following techniques:
• H33: Supplementing link text with the title attribute"

However the description for H33 does not support this. In fact one is cautioned against using this technique:
"Because of the extensive user agent limitations in supporting access to the title attribute, authors should use caution in applying this technique. For this reason, it is preferred that the author use technique: 
C7: Using CSS to hide a portion of the link text  or
H30: Providing link text that describes the purpose of a link for anchor elements ."

The How To techniques doc needs to be amended to reflect this note of caution. H33 should be made an advisory technique.
