Because when the tang location is inaccurate, that doesn't mean all 5 saddles are consistently inaccurate, it just means one or more can be off relative to the others.

The thrust bearing usually locates itself based on the slight press fit with the machined recess in the cap/block, not with the tang anyhow, and the position of the thrust is the main factor in how the crank is located in the block. Then the other four bearings use the tangs to "match up" to the position which the thrust has established.

If the tangs are machined correctly, this works great in theory. If they are machined incorrectly, you have a situation such as what is shown in the picture.
