Youtube vs Google, why they truncate title text in different way [on hold]

Recently I noticed how youtube suggestion videos truncate the title text without showing any ellipsis, it looked little incomplete to me. I was wondering if this is deliberate or some mistake. Google search on the other hand show ellipsis for long text.

It would be great if you can help me with any good reasons and drawbacks for these different behaviors. Why one of these can be more useful than another in any scenario.
