If he's on your friendlist the only reasons you'd not meet would be:
-Instance full
-Somone has a very high ping
-Playing diferent modes (Solo/group/open)
In my experience this is not the case. If I log on in a system and someone on my friends list jumps to that system and comes to the station I'm docked at we do not see each other, even if there are no other players in either instance. If we visit the same spots in that system (extraction sites, nav beacons, stations, etc) we still do not see each other. Once we jump to another system we do see each other and can play together.
Ping may be a factor because the person I've tested this with is in Canada and I'm in UK but we both have excellent connections to the internet and I've found this behaviour is repeateable.

Er...
Sounds like your issue is obvious, no?
