A question about Citi Corporate Banking's JD

Landed a FT offer from Citi for the Analyst post in Corporate Banking two weeks ago.
Was re-reading the JD and still couldn't figure out one partiuclar sentence ... so here it goes:

Citi’s Institutional Clients Group (ICG) is looking for full-time Analysts to join the Corporate Banking
team Corporate Bankers are relationship-focused finance professionals responsible for
understanding the wide range of complex financial issues facing our clients around the world. As a
Corporate Banker; you will drive the client dialogue on capital structure; liability management;
liquidity and funding strategies; risk management; and investment solutions. Unique to Citi;
Corporate Bankers are also responsible for deciding where to invest the firm’s capital and
executing on those investments. Corporate Bankers work in partnership with various Citi groups
across the firm including Risk Management; Investment Banking; Market & Securities Services,
Treasury & Trade Solutions and the Capital Markets Origination. If none of these terms make
sense right now; that’s ok! .............

Could anyone shed some light on that ambiguous part? Why is it unique to Citi? Is it becoz in other banks such decisions are not made by Corporate Bankers? "Invest the firm's capital" = lending?

Thanks a lot!
