Gotcha, yea there are a few data types in Premiere that are not undocumented and unable to be updated through the API or during runtime. Mask data, text data, among others fall in this category. Only workaround would be to reverse engineer the data, edit offline, and re-open the project file. Some have done it, but it's no walk in the park.

PPro offers no API around mask keyframe interpretation, nor is mask keyframe data documented.

Justin is correct; however, relying on parsing of undocumented Adobe data structures is neither supported, or recommended.
