This is a simple example with only two feature branches, and it's already a bit hard to follow. Imagine it with even twelve which is not even that many branches: * Merge Branch 'B' into 'main' |\ * \ Merge Branch 'A' into 'main' |\ \ | | | | | * B Commit 2 | | * Merge remote-tracking branch 'upstream/main' | * | A commit 2 | * | Merge remote-tracking branch 'upstream/main' | | * B commit 1 | |/ | * A commit 1 |/ * Compared to a commit graph where feature branches are rebased to replay their commits against the tip of main before merging: * Merge branch 'B' into 'main' |\ | * B commit 2 | * B commit 1 |/ * Merge branch 'A' into 'main' |\ | * A commit 2 | * A commit 1 |/ *
