Though it's not stated explicitly, this same behavior is applied to many built-in operations where an implicit RCL of a variable is executed. I can't remember the details at the moment, but I'm pretty sure there are at least a couple exceptions to this rule. It all boils down to which SysRPL opcode is used to get a variable's contents onto the stack. Most of the time the parent directories are searched.

Note that this isn't the same as searching all directories. Just the ones in the current path are included.

It is indeed something fundamental to understand.
But this being said is that the right way to go? The calculator would naturally feed the root directory with a lot of crap and a purge is tedious; my conception of a directory is precisely to isolate/encapsulate problems in their own context. So when I create a subdir I would expect to start with a blank page.
In my humble opinion, this mechanism totally ruin the concept of directories.

It is easily dealt with by creating a temp directory and doing your manual calculations and scratch work in there. When you have a stroke of genius simply move your program to a new directory. When the scratch directory gets too cluttered just delete and create it anew.

You don't download files and save your work to your computer's root directory, do you? While a computer does not inherit everything in its parent directories like the 50G it is just as poor in form. I guess the difference makes sense if you think of the 50G as being different from a computer - it is a customizable math environment.
