NR SSB beam freq change events

There are ssb change events in L1 which is triggered by UE.
For the same frequency and PCI, serving beam is changed to target beam for instance 0 -->2 and after less 200 ms, 2>>0 again , as far as I know this is the control of UE and no L3 event. Which means eithers beams are not seperated , overlapping a lot or UE thresholds to switch beam is too short.
The question is that pingpong could affect throughput in DL ?
