Maybe it shouldn't. Albert has quite a bit in common with Steve, right down to being frozen for decades, but as there's no reason to share that, he's not going to. "You sound like you enjoyed your work."

Someone else and Albert might have been uneasy with that fact, but Sam doesn't seem like the type of person to enjoy weapons testing for the sake of the pain they can inflict. Unless he's a sociopath; it's not like Albert knows for certain. He'd prefer to act on the assumption that the other man is as he appears, though.
