The tuners do NOT use the same lineup. One lineup analog, one digital. 
There should have been no overlap, but Rogers Cable is clearly 
double-casting 3 channels, once as analog and once as digital, since 
zap2it has those 3 with the same xmltvid ( and, viz. another thread, the 
same callsign). But the presence of the 3 channels should not trigger 
the removal of the another 32 analog channels.

More testing required, obviously...
