The money which has been put to FFIS or SPI has been earmarked "DebConf",
not "Debian".
AIUI, Debian is an SPI affiliated project, while there is no "DebConf" affiliated project, so any "DebConf" mentions in the SPI accounts are just for Debian's convenience.
I don't know about FFIS, though I was under the impression that the situation was the same there.
