A HUP tells nagios to re-read it's config files and apply any changes.  
I suspect that you have retention enabled though and that does change  
how some host/service parameters behave on reload/restart (yours is  
one of them).

"Retention Notes

It is important to point out that several directives in host and  
service definitions may not be picked up by Nagios when you change  
them. Host and service directives that can exhibit this behavior are  
marked with an asterisk (*). The reason for this behavior is due to  
the fact that Nagios chooses to honor values stored in the state  
retention file over values found in the config files, assuming you  
have state retention enabled on a program-wide basis and the value of  
the directive is changed during runtime (by submitting an external  
command).

One way to get around this problem is to disable the retention of non- 
status information using the retain_nonstatus_information directive in  
the host and service definitions. Disabling this directive will cause  
Nagios to take the initial values for these directives from your  
config files, rather than from the state retention file when it  
(re)starts. Using this option is not recommended, as it may result in  
some unexpected (from your point of view) results.

Alternatively, you can issue the appropriate external command or  
change the value of the host or service directive via the web  
interface, so that it matches what you've changed it to in the config  
files. This is usually done by using the extended information CGI.  
This option takes a bit more work, but is preferable to disabling the  
retention of non-status information (mentioned above). "
