Discrepancy in the note for TimeClip

[uid11]

There may be a discrepancy in the note for the abstract operation TimeClip (https://tc39.es/ecma262/#sec-timeclip).
The note mentions step 4, but the TimeClip algorithm at that moment contains only three steps.

      <emu-clause id="sec-timeclip" aoid="TimeClip">
        <h1>TimeClip ( _time_ )</h1>
        <p>The abstract operation TimeClip takes argument _time_ (a Number). It calculates a number of milliseconds. It performs the following steps when called:</p>
        <emu-alg>
          1. If _time_ is not finite, return *NaN*.
          1. If abs(_time_) &gt; 8.64 &times; 10<sup>15</sup>, return *NaN*.
          1. Return ! ToInteger(_time_).
        </emu-alg>
        <emu-note>
          <p>The point of step 4 is that an implementation is permitted a choice of internal representations of time values, for example as a 64-bit signed integer or as a 64-bit floating-point value. Depending on the implementation, this internal representation may or may not distinguish *-0* and *+0*.</p>
