Isn't this the situation that normally leads to displacement?

Understood that displacement generally sucks from POV of the affected pilot(s), so I'm certainly not cheering the idea--it's just, my (likely flawed) understanding of why procedures for displacement exist is "too many pilots in category X; fix via displacement."

Is that not how displacement works? Is displacement so costly to the company that it's better to be imbalanced & start DH'ing guys around to fill the gaps? An attempt to avoid training requirements [goes to the cost issue, I suppose]? Or is this an attempt by the company to "work with" people?

As usual, I'm sure I'm missing something....
