facts:
DA RD-7402 RD
DA 8SP bar end shifters
FH-M550 7SP freehub
knowns:
the RD-7402 can be used with 'alterative' cable mounting to behave
more in line with other Shimano RDs
the DA 8SP bar ends have the same cable pull as all 9SP Shimano
shifters/brifters
the FH-M550 will accept an '8 of 9' cassette scheme
unknowns:
Will the RD-7402 shift an '8 of 9' cassette on the FH-M550 freehub
using the 'alternative' cable routing?
Any and all help appreciated!

I think you're mistaken. The alternative cable position is used to increase
derailleur travel per click - to make a newer (7700) derailleur behave like
a 7402, for example.

Right.

No (see above), but just about any other Shimano derailleur with standard
cable routing will.
