When I checked the manual for values of bool types, it says as follows: " Boolean values can be written as on, off,
true,false, yes, no, 1,
0 (all case-insensitive) or any unambiguous prefix of these." Now "of" can be considered as unambiguous prefix of
"off",so it
might be intentional. Please refer below link for more detailed description:
