It's not the same as Respawn, Melinda, or Tenji who were all explicitly stated to be their siblings without a shadow of a doubt.
With Lincoln March, they went out of their way to say "well he's probably lying, my brother actually died as a baby so it doesn't matter", and pic related was confirmed to not be Bruce's brother at the end of his story.
They haven't 100% committed to the idea of Bruce having a brother, they've just teased and implied it, which isn't really the same as introducing a new character and confirming they're siblings right away like they've done with the others.
