multiple instance's collison or overlapping

As far as I understand from https://www.scirra.com/manual/75/how-events-work it's imposible to check overlapping or collision of multiple instances ("It would be very difficult to make good games if every bullet hurt every monster!") per frame or tick. So several frames will pass to handle situation when several bullets achieve goal (several goals) practically simultanuosly. I mean all bullets are instances of one object as well as goals. Is it correct or I missed something important and simultanious detection of overlaping and collision is possible yet?

The comment about every bullet hurting every monster refers to picking specific instances of an object...

If anytime a bullet hit a monster, ALL monsters on the level take damage is what it is referring to.

That paragraph is talking about "picking" instances.

Thanks a lot for answer, excuse my misunderstanding and poor English. Now it's clear.
