The signs aren't close to each other. It doesn't appear confusing standing in the station. The photo seems to have been taken from a distance, and this is only a small portion of it.
With it's unusually large and open mezzanine, Main Street has to be one of the easiest stations to navigate. Though the recent installation of a sign near above the front doors that says it takes 10 minutes to walk the 300 metres to Danforth GO is misleading.
Now that Walter has raised this thread from the dead, I'll note that about 3 years after this February 2016 post, TTC changed the sign showing the distance from TTC Main Street to GO Danforth from 10 minutes to 5 minutes. They'll probably have to replace it again now, to put a black T on it ...
Here's an August 2019 photo I took. The first time I noticed the new sign was July 2018. And I've got a November 2018 photo when it still said 10 minutes.
