My interpretation is that this is to support:
1. `loadDialectModule("my_dialect")` - doesn't find module
2. `append_dialect_search_prefix("path/to/my_dialect")`
3. `loadDialectModule("my_dialect")` - finds module
 
So its not about reloading existing modules, just loading new ones. Without clearing `loadedDialectModules` you'd end up hitting the early exit in `loadDialectModule`.
