in TS config for pages?

remarkable if both TS config for pages and TS config for users/user 
grous use the same config propertie?

But at least if not, the meaning of the id is nonsense.
I tested
$this->modTSconfig = 
t3lib_BEfunc::getModTSconfig($id,'mod.web_txtemplavoilaM1');

the value of the 'id' was 999999 and there is no such page.
The infomation should not exist but the result was the same
as setting
$this->modTSconfig = 
t3lib_BEfunc::getModTSconfig(0,'mod.web_txtemplavoilaM1');

because the first parameter for getModTSconfig seems to be nonsential,
why it exists overall?
