It could. but doesn’t have to do with module unloading, as
module unloading is inherently unsafe in Project Oberon 2013.

If a newly loaded module overwrites a previously released
module block, the system is left in a potentially unsafe state.

For example, procedure variables or type tags may still refer
to the overwritten module block.
