More probably, in my conjecture, prior to the advent of IF, there was a subroutine to evaluate the COND parameter and determine whether to skip the step. As a performance feature that I'd deem gratuitous, that subroutine was bypassed for the first step. When IF was provided, the logical place to add the code appeared to be in that COND subroutine which is not entered for the first step.
Or, perhaps the intent was to make the behavior of IF consistent with COND. ObEmerson. Much of this could be repaired since the JCL Ref states that the behavior of unspecified IF constructs is unsupported and subject to change.
