question

That's not really how the label matching functionality of the Wait For Event works. The Release Batch event passes in an array of the batched tokens. If you say to match that with the listening token's team label then it's going to compare the array of batched tokens with the number on the token's team label and never match. The matching option is useful if you have a reference to a specific token on a label and you're waiting for that exact token to trigger an event.

I've modified your model to show a couple other ways of doing this.

The first method uses a Wait For Event that listens to the OnExit of the batch activity. I'm then assigning the exiting token to a label on the listening token. The listening tokens go to the following decide and then use that newly assigned label to compare team labels. If they don't match the token returns to the Wait For Event.

The second method uses a Synchronize activity with a PartitionID of token.team. This might not be what you want though since this will also make the tokens on the left wait for those on the right.
