That was a rookie fund manager's move, using your most liquid asset to fund your least liquid.
In the olden days proprietary traders/stock jobbers/proto-market makers would keep their share and bond certificates in a box—hence short against the box etc. And in that box the most speculative, least-liquid-in-a-crash certificates were on top ready to be tossed into the maw of a descending market, with the highest quality, most liquid shares at the bottom of the box.
It was a tell as to either the individual trader's finances or to the depth of a downturn to see certs from the bottom of the box coming onto the market.
As a side note, you can still get your stock in certificate form but it will cost you at least $500 per cert. The powers that be, Depository Trust, the brokers et al. really prefer you don't ask for the paper.

"Though SBG's liquidity position has improved relative to when it issued its hybrids in October, we still estimate it will need to be proactive funding its recent (more than) $41 billion investment spend," she wrote....
