Sabbat Priest - how much of blood?

is there any general rule about resolution of multiples of the same effect?

To be precise:

Sabbat Priest
Cardtype: Political Action
Requires a ready Sabbat vampire.
Choose a ready Sabbat vampire. Successful referendum means that for the remainder of the game, any vampire attempting to block the chosen vampire burns 1 blood.

This is most recent card text.
As far as I understand, it is possible to got the same vampire to become sabbat priest several times, adding virtual "any vampire attempting to block the chosen vampire burns 1 blood" many times to their card - am I right ?

If so - does blocking vampire burns 1 blood (satisfying the logical / semiotic requirement), OR does it make them burn 1 blood for each virtual "any vampire attempting to block the chosen vampire burns 1 blood" ?

If the latter - where is it stated in general rules?

By default, you can apply the cardtext of each card individually.

Thank you, venerable Ankha.

May I humbly ask for the source of this ruling of applying each cardtext individually?

Also - this particular card causes
" for the remainder of the game, any vampire attempting to block the chosen vampire burns 1 blood "
card(s) themselves are long gone in ash pile, and not attached to the vampire.

So it ads virtual text to vampire card, I think ?
Is there any general rule how to resolve it?
