Heart of the Underdog question

Ok, so here it goes:

Assume I control one Heart of the Underdog, during my Draw Phase I keep drawing Normal Monsters until I draw a quick-spell such as Reload, can I activate it during the same Draw Phase and keep drawing (provided there's a Normal Monster among the cards drawn by the effect of Reload)? Just want to make sure... Thanks.

"If you draw multiple cards at the same time during your Draw Phase, such as with "Reload", only 1 of the cards needs to be a Normal Monster to trigger "Heart of the Underdog", since they are all drawn at the same time. If you activate "Reload" in your Draw Phase and draw 5 Normal Monster Cards, your "Heart of the Underdog" only activates 1 time because it says "card(s)"."

Yes, you can keep drawing

Thanks. It got me wondering cause the other day I was watching a video of someone using an Underdog Exodia deck in Yu-Gi-Oh! 5D's WC 2011 and it looked like they couldn't use Reload with just one Heart of the Underdog on the field:

Or maybe they just didn't want to? Or maybe it's some bug in the game...

Its not bug, the game just doesnt ask if you want to activate the card in DP because that´s how its programmed, if you hold the A button in the exact moment you draw Reload the game would give you the option to play that card and continue to draw
