In "normal" circumstances there shouldn't be hydrogen venting from any modern car battery, AGM or standard Lead-Calcium. But apparently it still can happen often enough to be a safety issue.
Given the results of a spark if the battery does emit hydrogen, it's not worth chancing unless you want to learn braille.
Yes, it's safe for the charging system to connect the negative leads to the same location where the battery terminates, just not on the battery negative itself (this puts it on the wrong side of the current sensor).
