Seems so. I assume this code is in file mog.jam? Then, your generator will 
call action rule using fully qualified name 'mog.msvc.link.dll'. You then 
import msvc.link.dll into the 'mog' module and define your own 
'mog.msvc.link.dll'. But, the latter definition is in mog module already. 
Fully qualified name of it is mog.mog.msvc.link.dll. As a result, your rule 
definition is simply ignored. Try adding ECHO statement to it.

Another issue is that inherit-flags assigns inherited flags to the 
'mog.link.dll' rule. (The flags are assigned to specific rules). So, those 
flags are not used for 'mog.msvc.link.dll'.

I think if you rename the generator and the rule to "mog.link.dll" things will 
work.
