Waveform generation VIs

Question

When a waveform generation VI is used in code, will it not keep
generating as long as the code is active,  till the Reset node (
if available ) is pulled high ?
But it appears that to do so, the waveform VI has to be inside of
a  while loop. I tried to run a while loop and a function
generator VI outside of it as a trial . But found that, after the first
call, the waveform VI was idle and it was only the while loop that was
executing. Can someone clarify on this.
I would have expected that the function generator VI  to start and
continue till the whole code containing it is stopped. Is that too much
to expect

Along the same line, I noticed the same comment in the help file:
"This VI remembers the time stamp of the previous waveform generated and continues to increment the time stamp from that point"
Seems to me that the VI should be keeping track of the Number of Samples and the Sample's Per Second based on the last time the VI was run (whether in a loop or not) So why is it that this VI seems to rely on the sampling rate of the loop itself? If I increase the Millisecond Wait Time my generated signal slows and when I decrease my millisecond wait time my generated signal updates much faster.
