A question about voided villagers

[ShenkuuBlossoms]

Okay, so a few weeks ago Whitney moved out of my main town unexpectedly. I had turned off wifi on my dses in prep for a plane trip and didn't cut it back on until almost 2 week later. Almost immediately after tagging, Whitney's plot showed up in my second town. Upon introducing myself to her, Whitney said she came from my first town, but she had been completely reset to 100% original, which she was not when she left (shirt, catchphrase, and house were altered).

So my question is: does being in the void for a certain period of time reset villagers?
