Here is an excerpt from my gdb output from following your instructions.
(I made the breakpoints conditional on the buffer being *scratch*.) It
looks like your guess is correct, since there is a save-excursion in
tramp-sh-handle-file-attributes wrapping code that executes commands
on the remote machine.
