Before I answer that... you've obviously got programs in your collection that are bigger than 2K... take a subroutine, place it at the beginning of your program and compile... then extract that same subroutine and place it at the end of your program and recompile... note the difference...

What doesn't happen in the bottom 2k that happens elsewhere? Think assembler level... OK, I should add a rider to that... it doesn't apply to really simple subroutines... rather the more complex ones... I've got into the habit of putting ALL subroutines at the start...
