I'm fairly sure that's correct. I certainly have a BA23 with two

I think it's worth pointing out that people
should never even try
connecting two hard drives in a BA23. You'll definitely wreck whatever
contents you have on the disks if you try.
It is my understanding that this was true for older BA23 chassis,
with only 4-button control panels. Ultimately, the problem was that
the Ready and Write Protect lines were floating for the 2nd drive. Patching a pair of 10K resistors onto the 4-button
control panel
was all that was required to make the 2nd drive function normally,
although admittedly, I can't recall if they needed to be pulled
high, or low.
IIRC it was one of each.
Power supply loading may come into play,
depending on how many drives & boards you have.
That too is true, but with drives that are less power-hungry than some
of DECs, less of a problem.
