Jansa's plans involved the extensive utilization of the Fatherland Front's affiliated militias (which had been merged into a single command in 1936). These would have served both on the front lines and domestically (against pro-German segments of the Austrian population). The paper makes no mention of such, but I imagine blocking detachments could be easily set up if the Austrian army's moral and loyalty was an issue*.Does that paper account for loyalty issues among the Austrian army? It may not matter if they have the theoretical strength to stop the Germans. If the soldiers support the Anschluss, they might not fight.
*and on that note, I wouldn't be so quick to assume that it would be, as the paper notes:
"Moreover, the fall manoeuvres and trial of the "Jansa Plan" in the forest area of Lower and Upper Austria (Waldviertel) depicted a skilled army full of enthusiasm and spirit. 221"
Doesn't sound like a force eager to help destroy its own country.
