If you view the details on the SEC form, you will see these represent different classes of shares. One is class A common shares and the other one, the larger amount, represents class C capital stock.

The Class A GSUs entitle the Reporting Person to receive one share of Alphabet Inc. Class A Common Stock for each share underlying the GSU as GSU vests. The GSUs vest as follows: 1/72 of GSUs vested on May 25, 2013 and an additional 1/72 vests monthly thereafter until the GSUs are fully vested, subject to continued employment on such vesting dates.

The Class C GSUs entitle the Reporting Person to receive one share of Alphabet Inc. Class C Capital Stock for each share underlying the GSU as GSU vests. The GSUs vest as follows: 1/72 of GSUs vested on May 25, 2013 and an additional 1/72 vest monthly thereafter until the GSUs are fully vested, subject to continued employment on such vesting dates.

As of October 19, 2018, there were 298,971,186 shares of Alphabet’s Class A common stock outstanding, 46,879,767 shares of Alphabet's Class B common stock outstanding, and 349,615,045 shares of Alphabet's Class C capital stock outstanding.

These different classes of shares represent different voting rights / liquidity. The sum of these classes is the total number of shares outstanding for the company. So what the table is showing under "shares owned" is only the number of shares attributable to each class rather than the sum of all classes of shares owned by him.
