Two directed loads into the same area would clearly be an error (unless the user of the first load was fully done with it).
There is no reason to fully serialize two directed loads any more than there is reason to fully serialize two loads of non-reentrant modules. Each will get their own storage, will do their own load into that storage, and will do the relocation into that storage. As with many things there is a lot of serialization amidst the processing, but it is not necessary to wait for "load 1" to finish before dealing with "load 2" unless they are sharing control structures (as happens for reentrant). Directed loads have no persistent control structures.
