Subject: Thread.start(variables) do question

So I have been looking at some code I inherited. I see two examples of
thread use in this. Wondering what the difference is. I've made up two
examples that show this, wondering what the difference is, and why to
use one or the other.

---Example 1-----------------------------------------------------------
obj1 = SomeObject.new()
obj2 = SomeOtherObject.new()
obj3 = "helloworld"

Thread.start(obj1, obj2, myString) do |thing1, thing2, thing3|
  #use the variables named thing1, thing2, thing3.
end
-----------------------------------------------------------------------

And then this way...
---Example 2-----------------------------------------------------------
obj1 = SomeObject.new()
obj2 = SomeOtherObject.new()
obj3 = "helloworld"

Thread.start() do
  #use the objects named obj1, obj2, obj3
end
-----------------------------------------------------------------------

So, What is the reason for doing Example 1 versus Example 2. The 2nd
example seems simpler in my book.  My guess is it has something to do
with how the objects may be used outside the thread?
