primaryPath cellgroup1 and ul-DatasplitThreshold infinity in NSA

Hi Experts.
In NSA, if primaryPath cellgroup1 and ul-DatasplitThreshold infinity, that means that all UL data are going via NR?

I would say yes.

Yes, but It depend on how the NRtoLTE UL based on SINR value switch itself.
If it’s enabled then infinity will be not valid anymore.
