If I read that paregraph correctly, what Turkey does not want is more Kurds. They would be willing to go to war with another state, just to make sure that Syria's Kurds, stay in Syria. The bottom line is that it would not be humanitarian concerns that would prompt Turkey into action, but rather domestic concerns.
At the moment I am fairly confident that Turkey has no plans to do anything - Mostly because Debka reported that they were invading syria a few days ago. Experience has shown that what Debka predicts/reports just never ever ever happens (or we would have all died long ago). However if the last few months have taught us anything - it is that the Middle East is totally unpredictable.
