Yes, a lock/unlock event affects the whole flowgraph, by necessity.

Reconfiguring flowgraphs should be considered a very big hammer, often
used in cases that can be solved some less invasive way.

Just in case anyone is looking for a less invasive way to dynamically configure a graph…

I just tried out Copy block and it seems to be a great way to turn on and off segments of a flow graph. I was locking & unlocking a graph to remove and add blocks.

This seems more elegant and prevents any problems with the WavFile-Sink.
