The morality police in Iran have been ordered to stand down.
All this means in relation to the Second Signpost is that the Basij has one less job to do. The regime likely told them to stand down to reduce the agitation towards the great majority of Iranians who hate the regime, in light of the last three months of protests.
The Basij is the large pool of volunteers from which the IRGC gets its recruits. The Basij was there before former President Ahmadinejad made them the morality police, and they will be there after.
The Basij, the IRGC, and the whole regime will be ended during the Third Signpost.
