Does pleading guilty to each of the three counts of sexual assault prevent the government from presenting evidence to establish that each counts is distinct?

1 The government has argued that by pleading guilty, the appellant precluded the government from presenting evidence to establish the distinct nature of each of the three counts. The government relies upon United States v. Gumbs, 246 F.2d 441 (2d Cir. 1952). The majority opinion of that panel relied upon an affidavit by the prosecutor; here we have no affidavit and presumably only supposition.
