Well of course they are!

You can use it anywhere you have the same sequence of POPS followed by a RET

And in the case in point the original designer simply always used the 
same registers - AX, BX, CX, DX - as scratch storage in any subroutine.

And because I was modifying and extending his BIOS code, I followed the 
same convention as well.

When you needed to cram more into an already full 2K EEPROM it was a way 
to do it.
