question

The issue is that the match operation doesn't match labels on the two tokens like you are expecting it to. It matches the token that just entered the activity you're listening to with the value on the label you specify. So your setup is saying:

Wait until a token arrives that matches the value on my Dry Room use label.

And so the comparison looks like this:

3 (value on the Dry Room use label) != The token that entered

I've attached an example model that shows a couple other ways you could synchronize by matching labels on two different tokens.

The first uses a synchronize activity with the label value as the Partition ID. This, however, will cause both tokens to wait until they are matched up.

The second uses a list to synchronize. The tokens on the left pull from the list and the tokens on the right push themselves on the list momentarily before removing themselves and moving on. This notifies any tokens on the left that are waiting while letting the tokens on the right move along without waiting. Both push and pull operations use the label value for their partition ID's.
