Because machine B is the fastest of them all and machine A has all the
important filesystems (home src etc...).
The reason for a /vol/src is that this way if I want to build a
-current machine I can just link /usr/src to /vol/src/FreeBSD-current/src 
instead of .../FreeBSD-stable/src.
/scratch on machine B is a wipeable 1GB partition that I can use for
anything from (several) buildworld trees to cd images.
Nothing important is on machine B since it occasionally runs another
OS the name of which I will not mention, but the fdisk that comes with
this other OS has it's "peculiarities"...
But your sugestion will work fine none the less, I just like to things
different then other people sometimes. I do believe there is a word for
that ;-)
