Audience Streaming - Journey Action ID

Hello all, 

I have a two (2) separate transactional journeys - English and French. We have an edge case where a person can use submit their email address and receive the Welcome message associated with the respective journeys; which is not what the client wants to happen. 

I tried creating a Streaming Audience where I look for anyone in the past 24 hrs who may have received the email message (using the Journey Action ID), and used it as a Condition to check if the email is not in that audience it should receive the Welcome. 

However, when I go to test it, I will can submit the English version, and on the same day submit the French version and receive an email. I would think that any email sent from those Journeys would instantly be added to the audience since I'm streaming it, but that's not the case. 

It seems as if the audience is still be treated as a Batch. Is there something I'm missing when creating a Streaming audience using the Journey Action ID. I would assume that any email sent is instantly updated in the Message and Tracking logs, which are associated with the Profile by the primary key created when a new profile is added via the Welcome. 

What am I missing?
