What made Shiv Sena backout

What changed in the few hours of the Shiv Sena issuing a whip declaring support for the BJP against the No Confidence Motion and later deciding to abstain itself from the proceedings?

The party was mainly worried that if the alliance with the BJP does not happen for the Lok Sabha and the Assembly polls then the party would have no face to show. “ How can you call this the worst government ever and then vote for it in the Parliament. If there was no alliance this would have come to haunt us.”said a Sena Leader.
