No.
They are similar, to the point of the exhaust gasses going into the turbine, a twin scroll has two separate inlet nozzles inside the turbine housing. These start at twin entry inlet and run all the way through the housing separately, right up to the turbine blading. See the attached picture. See how the red and yellow exhaust gasses start seperate and hit from separate nozzles inside the casing?
True twin scroll
The twin entry, single scroll is similar in that the exhaust gasses enter the housing, but then, rather than hitting the blading in 2 different gad paths, they join up into 1, just like a single scroll turbo. Basically looking at the picture, the red and yellow gasses would join inside the inlet to the turbo. They become 1 just before the blading, rather than keeping them separate until after hitting the blading, so to speak.
Hope that makes some sense
