Two ETFs overlap when they hold the same underlying securities. Holding both funds can leave you more concentrated than you think — you may own the same large companies twice, at a combined weight neither fund shows on its own. The weight overlap above is the share of portfolio weight the two funds hold in common: for every security both own, it counts only the smaller of the two weights (the slice you genuinely double up on). 0% means completely different books; 100% means effectively identical funds.
