confused about patching 5.0

Hi all

I've updated two esxi 5.0 boxes with the latest patch ( update-from-esxi5.0-5.0_update01 ) as advised by the page:

http://www.vmware.com/patchmgr/download.portal?rct=j&q=&esrc=s&source=web&cd=1&ved=0CFsQFjAA&url=http://www.vmware.com/go/downloadpatches&ei=U03oT7vtIcm90QXq5qnvCA&usg=AFQjCNEIHccddkleB6hOSnNbc3Fj3-VlwQ

Now on the console I can see built number 623860 which I guess it's the latest update for esxi 5.0.

However when I go back to the patch page as per above and I look for updates for esxi 5.0 built number 623860 it tells me that there's an update:

update-from-esxi5.0-5.0_update01

even though I've already installed it.

I this normal, am I missing anything here?

Thanks!
