Is the ECB trying to crash the bond market to save its QE scheme?

The global bond rout continues, Bund yields have risen tenfold while the prices have collased.

My first thought was that maybe the gov debt ponzi is starting to unravel, but the idea proposed on ZH here:
http://www.zerohedge.com/news/2015-05-12/global-bond-rout-returns-vengeance-10y-treasury-tumbles-under-key-support-futures-po
namely that the recent downswing is due to the ECB selling off parts of its giant bond portfolio to force yields higher, thus making a wider portion of it eligible for purchase under their QE scheme (which forbids buying bonds under the own deposit rate) makes sense.

Moar funny money to feed the system and moar interest to collect from the goyim, its a win-win.
