Maybe, but there's a dearth of evidence for this; if you can find
any, it would help.

Can't seem to find any, sorry.

What, there's no Wikipedia page? Shock, horror.

It's an interesting case, because the Heathrow Wikipedia page could
easily mention in passing when the scheme started, but doesn't. And
given that Heathrow logistics is hardly a minor issue, the lack of any
historical notes about it (even on BAA's sites) is a bit strange. You'd
think they at least would have some sort of local transport evolution
timeline.
