A Pulumi program executes effectively as a coroutine with the Pulumi engine, which calls providers and resolves future values in the program which allows more resources to proceed. The fundamental difference here is that in Terraform the graph must be known up front to produce a plan, whereas in Pulumi the graph is constructed on a more ad-hoc basis. Both approaches have merit in different situations.
