Most likely this is because they each give you something for using them (Benhart is needed for 3 fights to get his) so this will be one of those fights you have to go NG+ to get everything. It forces a second playthrough. another possiblilty is that this fight is really not that difficult and two summons would make it rediculously easy. I doubt this last one because many boss fights are easy enough solo and they still give the option for two summons. Or if we go lore wise maybe memories are fairly weak and do not have the power to hold multiple people that are not native to memory. The memories might be time traveling so maybe they do not have the energy to transport more than two people into the past. You yourself can only be there for a short period of time indicating there is some weakness in the memory access.
