This is the correct behavior.

From CLHS documentation of LOAD

load binds *readtable* and *package* to the values they held before loading the file.

So any reassignments to *package* made while loading a file are discarded.

This allows IN-PACKAGE to be used within the file to specify how the code in that file is processed, without having side effects on the user's environment.
