Which stocks do VIG and VO both hold?

The largest shared positions are PSX, TRV, MSI, CMI and CL. Ranked by the smaller of the two weights, which is the part you would own twice.

Is it redundant to hold both VIG and VO?

Out of every $100 split evenly between them, about $13 (half in each fund) buys identical positions. The rest is exposure only one of the two funds gives you: 256 names only in VIG, 194 only in VO. Half in each behaves like 163 equally weighted stocks, against 54 for VIG alone and 206 for VO alone. Whether that duplication is a problem depends on the mix you want; this is a description, not advice.

How is ETF overlap calculated here?

For every company held by both funds we take the smaller of its two weights and add them up. The weights come from the full holdings files Vanguard publish, not a top-10 sample, and companies are matched by their ISIN so share classes stay apart. Sector overlap applies the same rule to the issuers' sector labels; "behaves like N equally weighted stocks" is one over the sum of the squared weights.
