I think that would be the only innocuous reason to include that line, but nobody really asked. The treasury and the FDIC have both been taking a lot of actions, like setting up 12-figure lines of credit and having banks deposit money in each other, without the market really "asking" for it, which makes me think that there's a decent chance that something is actually wrong (my guess here is that Bank of America may be insolvent on paper, depending on the duration of their outstanding loans and bonds). If the FOMC believed the system was strong, there was probably a lot of debate at the meeting as to whether to include anything. If not, the line would be included 100%.
