[Edited:] Deleting some items in a collection appears to delete all of them

[See note at end, this is an incorrect description of a bug]
I am trying to find all items in a collection that do not meet a certain criterion, and it isn't working. This appears to be a general bug in static collections: if you filter a collection by a criterion, select all, delete those items, you actually end up deleting all the items in the collection.
Here is a recipe for demonstrating it
Put a bunch of items into a collection (I put in 20 items)
Go to the filter and choose a criterion that selects some but not all the items (I used Date: 200)
Select all (⌘A) and delete, you will get a dialog that says "Delete N references from Group?" Say OK, and clear the filter -- the collection is empty!
