I think you're reading the sub sections out of context.
The sub sections from 57.4.1 only apply if the section 57.4.1 is valid.
For 57.4.1 to be valid, there must be open vacancies.
For example, imagine a 6 year FO who just met command requirement. He/she can't go and then take a command position from anyone who was employed in the six years prior and demote them to FO - just because they are more senior. Again, before the announcement was made.
57.4.1 says "opportunities" - if this word was omitted, the above scenario could/would occur. But it does say opportunities, so this means vacancies.
I'm not sure what you mean by pilots don't displace pilots, the company does? I can't find it in the EBA.
