Is it redundant to hold both QQQ and XLC?

Out of every $100 split evenly between them, about $12 (half in each fund) buys identical positions. The rest is exposure only one of the two funds gives you: 93 names only in QQQ, 14 only in XLC. Half in each behaves like 24 equally weighted stocks, against 32 for QQQ alone and 10 for XLC 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 Invesco and SPDR 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.
