But it is how I would describe, in writing, the construct of nested Ifs:

  If A
    {DO THIS}
    If B
      {DO THIS}
Where there may be any amount of code, waiting or looping before you get 
to the If B and indeed the end of the If A statement.

Or perhaps:

  If A
    {Wait for B} -- specified or indeterminate wait time

Or perhaps:

  {Wait for A}
  If B
    {DO THIS}

In either of the above, A could become False at anytime after the test or 
after the wait as the test for B and the execution of the related code is 
not dependant on A.

The second one is simply

If (A) AND (B)

perhaps an interesting side step into logic, but pretty irrelevant to the
