Yes and no, perhaps.
Would they not be better doing one thing well (SOU-MME-ABZ) instead of two things badly (SOU-MME and SOU-NCL)?
I'm assuming there must be a reason they don't, but I don't know what that reason is.
SOU-BHD sounds to be doing OK for them, unlike MAN which is decidedly hit and miss.
