It matches because it's true. The expressions states any number of digits before the end of line. It does not state exclusively digits.

Perhaps the input value is being cast to an integer for storage, and so the trailing letters are being stripped out. IF the validation happens after the cast, that could explain it -- but only if the value that ends up being stored is actually free of letters.
