The reason is because there is no difference in today's pool jargon.
Games in which you can give the table back after a miss are called "call shot/call safe" or sometimes just "call safe" to denote that safeties must be called. Call safe is, by far, the worst form of rotation pool, which is what I think you are trying to say.
Not what I was saying but, I do agree that "call shot/call safe" sucks.
I've met people that use call shot rule to say:
Hey, you didn't call the 8 ball touching the rail as it went into the pocket.
Or
Hey, you didn't call the 7 ball touching the 9 before going into the pocket.
To me, call shot is NOT where you call every little detail but, call pocket is where you call the pocket and it doesn't matter how it gets there.
I understand at mid-level and above skill levels, we don't normally have to worry about such crap but, it seems every time I play in public rooms with strangers, especially on league nights in certain rooms, I end up hearing bs about it in one form or another.
Matter of fact, I met a fellow in Huntsville Alabama not long ago at goodtimez. We played one game of 8 ball. It sucked a55.
Long story short, we agreed to call pocket on all shots...... I called the 8 ball in the side and it hit the facing and went in. Lol....he argued that it wasn't a legal shot since I didn't call the rail first.
Thats exactly why I like to clear the air when someone ask "wanna play call "x"".
Like I said, its not a problem with most any reasonable person/player but, its always that one a55hat that you just don't expect to be like that.....until they are.
