It may work fine because you probably tested with a fairly complex script
that happens to call something that parses all the headers up to at least
your Event header before you called $hdr(event). The issue appears if you
use $hdr(something) before that header was actually parsed by other
means. It appears that using the short form of pvars doesn't suffer from
this problem, so if I use $cs and after I use $hdr(cseq) it works, but
the other way around it doesn't.
The minimal script below shows the problem. If you check the debugging
output, you will notice it doesn't even attempt to parse the cseq header
until $cs is used. after that $hdr(cseq) works as expected.
