The expansion of the contents of "$@", "$*", and $* are different, which results in the differing results. Assuming that a "b c" d e was entered on the command line, then "$@" results in this expansion on the for loop (quoting from the command line is preserved):
while "$*" results in:
Here the command line arguments are converted to a single token and thus the loop executes only once with "a b c d" assigned to x.
For the last example, $* (no quotes) evaluates to just a b c d on the loop statement (quoting from the command line is not preserved) and thus the loop is executed one time for each and thus each is presented on a separate line.

continue
continue(1T) Tcl Built-In Commands continue(1T)__________________________________________________________________________________________________________________________________________________NAME
continue - Skip to the next iteration of a loop
SYNOPSIS
continue
_________________________________________________________________DESCRIPTION
This command is typically invoked inside the body of a looping command such as for or foreach or while. It returns a TCL_CONTINUE code,
which causes a continue exception to occur. The exception causes the current script to be aborted out to the innermost containing loop
command, which then continues with the next iteration of the loop. Catch exceptions are also handled in a few other situations, such as
the catch command and the outermost scripts of procedure bodies.
EXAMPLE
Print a line for each of the integers from 0 to 10 except 5:
for {set x 0} {$x<10} {incr x} {
if {$x == 5} {
continue
}
puts "x is $x"
}
