I would guess it's just a coded limitation in simh. In fact, there is no 
real limit to the number of TS11 you can connect to a PDP-11.
It's just a Unibus device with a bunch of CSRs. You can always just add 
another card, if you wanted to, in the floating address space in the I/O 
page, until you run out of space, which definitely fits way more than 
four controllers.

But I suspect the four controller limit specified in the manuals are 
because of power and/or throughput limitation on the bus.

simh have lots of such limitations and restrictions on various devices 
you can add.
