AOE2DE - How to gather resources using ally Town Center.

Just tried out the wanderer gamemode where your villagers spawn in random places on map without a Town Center. I accidentally used up all my wood building a dock, houses and a mill. I realized I couldn't build a Town Center and had no way to gather wood. I asked my allies and one of them named pipixia told me to gather wood and then garrison my villagers inside his Town Center. I didn't think it would work but when I tried it the resources actually went into my stockpile! Not sure if this is a feature or a bug but it works!
