I hadn't really considered Smithers needing to be present whenever Half-Life 1 is played. The way I saw it working involved the Half-Life continuum, Headquarters, and World 1 not being simultaneous with each other: the Black Mesa disaster happens at a specific point in time in the Half-Life continuum, and when someone from World 1 plays Half-Life 1, they are in essence looking back in time to that period and playing through it, even though the two worlds don't run so that one second here equals one second there.
Thus, from his perspective and Half-Life's, Smithers left for the PPC some time between Half-Life: Blueshift and Half-Life 2 and never permanently returned to his home (which is why he does not exist in Half-Life 2). Since people playing Half-Life 1 are experiencing a slice of time in the Half-Life continuum from before he ever left, regardless of when in World 1 they decide to play the game, the old Smithers would still be there. In fact, if he did come back to Half-Life at the time of the Black Mesa disaster, a player might encounter two Smitherses: one who was working at the facility like he should have been, and one who will have escaped Black Mesa, left the continuum entirely in the very near future, spent 10 of his years in a place where time flows at a different rate, then traveled back in time to before he ever left.
