Not exactly. There is still the 2/3 requirement for a quorum. The Republicans are letting the DOJ know that they are adopting the "Bullock Precedent" which was last used when Bob Bullock (the great Democratic Lt. Governor--and President of the Senate) eliminated the "Senate courtesy" of a "blocker bill" that requires 2/3 of the Senate to approve before a bill comes up for debate.
Bullock also had to remove the "blocker bill" to get redistricting through 12 years ago.
