Set verbose Flag Inside if-block

[Sysadmin Lists]

What explains the difference here? Why does setting verbose inside the
if-statement not echo the command, but setting x does, and setting verbose
before the if-statement does, too?

$ if true; then set -ve; echo $-; echo foo bar baz; set -ve; fi
ehimvBHs
foo bar baz

$ set -ve; if true; then echo $-; echo foo bar baz; set -ve; fi
set -ve; if true; then echo $-; echo foo bar baz; set -ve; fi
ehimvBHs
foo bar baz

$ if true; then set -xe; echo $-; echo foo bar baz; set -xe; fi
+ echo ehimvxBHs
ehimvxBHs
+ echo foo bar baz
foo bar baz
+ set -xe

$ set -xe; if true; then echo $-; echo foo bar baz; set -xe; fi
set -xe; if true; then echo $-; echo foo bar baz; set -xe; fi
+ set -xe
+ true
+ echo ehimvxBHs
ehimvxBHs
+ echo foo bar baz
foo bar baz
+ set -xe
