Different set of values for mass share and mass assign goals in 25B

Hi, with the 25B update, we now have the functionality where managers can mass assign and mass share goals. However, we noticed that the values available in the 'Select' employees list is different for each action. Is this a bug or is this as designed, as we may need to explain to managers why they are different. Pls advise. Screenshots for reference.
