When we have both header expression (which has to be an OR node by construction) and a pattern expression (which could be anything), we create a new top-level OR node to bind them together, and the resulting expression structure looks like this: OR / \ / \ pattern OR / \ / \ ..... committer OR / \ author TRUE The three elements on the top-level backbone that are inspected by the "all-match" logic are "pattern", "committer" and "author". When there are more than one elements in the "pattern", the top-level node of the "pattern" part of the subtree is an OR, and that node is inspected by "all-match". The result ends up ignoring the "--all-match" given from the command line. A match on either side of the pattern is considered a match, hence: git log --grep=A --grep=B --author=C --all-match shows the same "authored by C and has either A or B" that is correct only when run without "--all-match". Fix this by turning the resulting expression around when "--all-match" is in effect, like this: OR / \ / \ / OR committer / \ author \ pattern The set of nodes on the top-level backbone in the resulting expression becomes "committer", "author", and the nodes that are on the top-level backbone of the "pattern" subexpression. This makes the "all-match" logic inspect the same nodes in "pattern" as the case without the author and/or the committer restriction, and makes the earlier "log" example to show "authored by C and has A and has B", which is what the command line expects.
