I suppose so... Not sure about the second part but for the first part I think that comes from the idea that I don't think we've ever empirically or even subjectively observed the universe in any other state than "now". We've never personally nor in a scientific experiment observed any physical system being in more than one state, and that one state has to by definiton be in the "now" (Unless I am mistaken). So the past and the future states are essentially nowhere to be found in empiricism ? As for the "here" part I am not sure how to respond to that but it sounds right - any observer has to have contact in some direct way (whether with a scientific instrument or not) to the thing physical system he is observing and as such claiming anything about anything indirect or far away is very hard if not impossible so you get the "here".
