How does it check for sammi spec if it allows brass over max length to git flush like it's in spec - Lyman Ammo Checkers

Got these to easily check brass length before loading. If it supposedly checks for sammi spec and headspace then i should be able to put a piece of brass in the guage and if it's over max case length then it shouldn't fit flush in the guage. But it does.
Loaded ammo or not, it should be verifying the case length because if the brass is over max length then it won't fit in any in spec chamber.
I've put pieces of brass that are 0.01" over max length and they still fit flush in the guage like they're good to go. Anyone that knows anything about loading ammunition knows that 0.01" over is a lot. The difference between most cases min and max length is 0.01". So another 0.01" over max is a lot.
Do not buy these. They're absolutely useless.
