Maybe the inclusive gateway suites your needs?

I think you are totally right about the behaviour since I've found the following definition from the BPMN 2-0 Specification BMI 09-05-03.pdf

"A converging Exclusive Gateway is used to merge alternative paths. Each incoming control flow token is
routed to the outgoing Sequence Flow without synchronization."
