Weird experiment trigger

I started experiment with terminal trigger. Accessed terminals in security, lab(remotely), office, cave. At the end of the day I was backtracking early rooms, looking for hammer, since security claimed it was somewhere(didn't find it). Reached security again and used terminal again. Reminded myself about recent Reddit post about >!Babbage, so I used her!< password. It obviously gave me incorrect password prompt, but triggered experiment 5th time. Tried other >!admin passwords and footage!< password, but I didn't get any more triggers. Any idea why using that password gave me +1 trigger, despite being incorrect?
