Thank you for the clarifications. Here in Brazil, even decent surge protectors with proper varistors (MOVs), thermal fuses and gas discharge tubes (GDT) are mainly referred as "line filters" by the companies that sell them. The higher end ones are referred as line conditioners in Portuguese, just like in English.

Also, thanks to an anon on the other thread, I got pointed to a Reddit page with good info on this: https://www.reddit.com/r/ECE/comments/47lmqy/why_is_there_always_a_capacitor_across_hot_and/
So that capacitor in my fake line filter is serving the purpose of a decoupling capacitor. Its main functions are to prevent arc formation when the on-off switch is set to off and filtering high-frequency noise.
