I cannot reproduce the problem with plain groff, but came across it when
using macro packages like mm or mom.

This demonstrates the problem:

.PRINTSTYLE  TYPESET
.HEADER_LEFT "top"
.START
text1
.NEWPAGE
.br
.rs
.br
.sp 5
text2
.NEWPAGE
text3
.NEWPAGE
foo
.br
.sp 5
text4

Put above into file "test" and process with

groff -mom -Tps test > test.ps; gv test.ps

and see, how text2 and text3 are placed with the same distance to the header 
rule.
For text4, groff finally honors the preceeding .sp 5

Cheers,
