Confusing state diagram in AN14145 - Flash Memory Swap Features on MCX N Series

Looking at AN14145 and Figure 2, I am somewhat confused about the error cases when the attempt to run the first "logical" image does not boot. I.e. the diagram gives this possible execution order:

 

Is there a second image file? Yes

Whether second image version is greater than first?  No

Start first image

Startup successful? No

Start second image

Startup successful?  Yes

Run first image

 

The last state should be "Run second image". The same problem exists on the symmetric case when the second image should be tested first and does not boot.

I know, it's kind of cosmetic, but its really confusing.  Would be good to fix this in the document.

Thanks in advance!
