I think this is using the term "asynchrouously" where others might use "off-line". When the meeting turns up a problem that isn't going to be resolved in a few words, you might prompt those involved/interested to organise a specific meeting rather than bore the rest. However, "Can we take that off-line?" can also come to mean "Stop bringing problems!" :-)
