That's because, when deciding to make a rule, make expands ALL variables in ALL
commands for that rule prior to executing the first command. Not as you have
thought: expand variables in first command, execute first command, then go on
for next command.
However, I have no idea why the make author chose the first way instead of
"expand one command, execute one command". The official make manual seems not
to have explained this.

Yes, I'm now working around like this, thanks again.
