It can be if it is infinite in other dimensions.
Please read the link I posted.
I did, and I was going to posit a thought experiment which I thought was going to help but it's convinced me that you are right if we qualify it that in a universe which is infinite in the spatial dimension then all things that can have happened in the time of that universe has existed, are almost certain to have happened multiple times. In a universe with a different time of existence, some things may have happened there that would not be replicated in the other universe.
I think though that in discourse about infinity if the term is not qualified it includes temporal infinity, though I accept that once the qualification is made , you are right.
