[R] double-click in RData file versus load( file )

hello all,

when I start up the R and I execute o follow code:

 > ls()
 > x=123
 > assign("test_x", x, envir = .GlobalEnv )
 > ls()
[1] "test_x" "x"     
 > setwd('C:\\R\\etc')
 > save.image('TEST.RData')
 > q('no')

I have two different behaviours:

(a) - when I start up R again by "double click" in the file TEST.RData;
(b) - when I start up R and load the file TEST.RData by window menu in 
Rgui or
invoke by command ' load('C:\\R\\etc\\TEST.RData')

In case (a): I can't see my previous variables anymore!
 > ls()

In case (b): I get my previous variables again!
 > load('C:\\R\\etc\\test.rdata')
 > ls()
[1] "test_x" "x"    

Is it the correct behaviour?
the two way don't must be the same?

Thank for explanations...

Cleber Borges
