Certainly, where countries faced collapsing growth and weaker inflation together, they could all move policy in the same direction. However, when the GFC ended and the pandemic ended, not all faced the same policy trade-offs. The GFC ushered in an extended period of ongoing QE and low rates, but this was not true for most emerging market economies.
The end of the pandemic has been different. It has thrown us all back into a pre-Great Moderation world in which inflation is super-sensitive to supply and demand shocks.
