This is correct. The way presenter works is that it loads the
first three slides up front (so with a video on each slide, the
load time may be a bit longer than expected) but then begins to
pre-load additional slides in the background, one every three
seconds. So, as long as your users are on a decent internet
connection then you shouldn't see any issue with this idea. It's
not the easiest method, but it will work. Be sure to use FLV format
for the videos and keep in mind the 102 Mb upload limit to connect
if you are going to be using that as your delivery method.
