Run global <script> before or after <datamodel> initialization?

The prose in the official algorithm describes a <script> element at the root of the document as being run after the data model is initialized:

"Create an empty configuration complete with a new populated instance of the data model and a[sic] execute the global scripts[sic]."

(I assume that "scripts" should be "script", as only one <script> element may appear as a child of <scxml>.)

This order makes sense to me: I want my script to be able to read initial datamodel values and manipulate them. (I'm assuming that script executes in the context of the data model and may thus set values in it as well.)

However, the official pseudo-code executes the global script element before the data model is initialized:

    datamodel = new Datamodel(doc)
    executeGlobalScriptElements(doc)  # Note: this is also plural
    ...
    if binding == "early":
      initializeDatamodel(datamodel, doc)

Is there a compelling reason to execute global <script> before initializing the data model?
