So right said Fred (qv), and here's the method. It's not much, so I decided to publish it with a few extra comments. oPages is an array property, and

Lpara oPageRef
lcFullName=SYS( 1272, oPageRef)
lnAt= ascan(this.oPAges,lcFullName)
if lnAt=0    && not visited yet
	This.lastpage=this.lastpage+1
	Dime this.oPAges[this.lastpage,2]
	This.oPAges[this.lastpage,1]=oPageRef
	This.oPAges[this.lastpage,2]=lcFullName
else    && aha, a revisit
	nLastpage=lnAt/2
* so discard later references
	for i=this.lastpage to nLastpage+1 step -1
		this.opages[i,1]=null
		this.opages[i,2]=''
	endf
	this.lastpage=nlastpage
Endif

So in the PrevPage method I'm only finding the reference to the previous page, and that would be this.opages[this.lastpage-1, 1], and then activate that page - and decrease this.lastpage by 1.
