You're thinking about Ant as a programming language. You assume that Ant
tries to execute your target, sees the depends, and then executes that
first.

Ant is a build description tool. The very first thing Ant does is to build =
a
complete matrix dependency of all targets and then executes the targets
based upon the matrix. It has no way of knowing at that point that target
"d" called target "a". It simply knows that to execute "d", it must execute
"a" first.

Use the -default flag, and you can see it build the build dependency step.
