Very good explanation. I tried something: # a=1;a=2;a=3 | echo $a (outputs 2). So, It got second 'a' value in the output, and not the first one. @pizdelect

The ; has lower precedence than |. You're not fooling the parser by huddling the assignments close together -- the parser will still group it as a=1; a=2; { a=3 | echo $a; }, not as { a=1; a=2; a=3; } | echo $a. Just like 4+4 / 2 is 6 not 4

Got your point ! It should be considered precedence order in command execution by Bash
