Do I get infinite troops?

[taltamir]

using the trick to check the amounts I noticed the following:
1. When something becomes horde, it gets +9999 units. So if I had 25 archers left and then was promoted, the horde of archers will list 1024 units. Since I used my swordsmen up, it listed 9999.
2. No matter how many you buy from a horde stack, it never goes down.
