Why is Ka4 no alternative solution?

Why is

1. Kxf3 Ka4
2. Ke2 b3
3. Ne3 b2
4. Nxc4 b1=Q

not even mentioned as alternative solution?

1 ... Ka4 is met by 2. Ne3, which draws. Here are some typical variations:

1. Kxf3 Ka4
2. Ne3 b3
3. Nxc4 draw

1. Kxf3 Ka4
2. Ne3 c3
3. Ke2 b3
4. Kd1 b2
5. Kc2 draw

1. Kxf3 Ka4
2. Ne3 Kb3
3. Ke2 c3
4. Kd3 draw

thx for your explanation and the examples.

But what about

1. Kxf3 Ka4

and then (for example

5. Kc1 Ka2

or

5. Nc4+ Ka2

or
