Thank you for your question @isolda! It is possible to have an activity
with two audiences for the same test, however the audiences must be
mutually-exclusive. From our documentation about multiple experience
audiences in A/B tests here, you'll see that if a visitor matches more
than one audience (which in this case they would due to the "All
Visitors" setting), then the content for each audience will be returned
and will push down the visitor's relevant content. In this case, it
would be helpfu...
