It takes some work to decipher his notation, since he deals with more general weights. It's essential here to be working in two blocks which are equivalent, so you can translate parabolic Vermas back and forth when the simples correspond under translation. These subcategories can get tricky, since not all "admissible" composition factors of a Verma module need to survive in the parabolic Verma module constructed as a quotient. | |
