They are aliases. If you look, you see that for and foreach have been used differently. This should clarify that.

#!/usr/local/bin/perl5.9.1
print "foreach1...\n";
foreach (Foo->new) {}
print "after foreach\n";                                              
+                                  

print "for...\n";
for (my $object = Foo->new; 1 < 0; ) {}
print "after for\n";                                                  
+                              

print "foreach2...\n";
foreach (my $object = Foo->new; 1 < 0; ) {}
print "after foreach\n";                                              
+                                  
package Foo;
sub new { my $self = bless {},shift; print "CREATED $self\n"; $self }
sub DESTROY { print "DESTROYED $_[0]\n" }
