Which would be a technicality Scotty would be quite annoyed with - he didn't want any "bloody A" to mar his trip down the memory lane.
The fact is that Picard would know nothing
about Scotty's dream ship if he were only familiar with the refitted Constitution
class: the refit created an "almost completely new Enterprise
" as stated in ST:TMP, a ship unrelated to Scotty's simulation in anything but name.
From Scotty's POV, Picard is being a pal. From Picard's POV, he's telling a (rather white) lie if he has visited a refitted museum piece.
