Except when Superman describes the Crime Syndicate he uses the present or future present tense. If they were gone he should be exclusively using the past tense.

More over in the Post-Flashpoint Prime Earth history they came over once not "often" as those not killed at the end of the Forever Evil storyline got a serious case of dead by the end of the the Darkside War saga. So that aspect of their interaction with Prime Earth changed so why not their deaths?

As mentioned in the EARTH 2 & CRIME SYNDICATE QUESTION (SUPERMAN #9 SPOILERS) thread over at CBR hypertime plays total havoc with continuity - history is misremembered or even altered as various timelines of an Earth interact with each other. It is to put it bluntly a mess. Never mind there it has been demonstrated there are 53 universes in the local multiverse.
