My reading of Tulane’s rules for SCEA is that he cannot apply EA or ED to any other schools, but he still can apply “early” for regular decision. This is not a major restriction. The only thing to avoid is EA or ED at any other schools besides Tulane.
Applying regular decision, but early, can be almost as good as EA or ED. For example, I know two young people here in Ohio who applied regular decision to Ohio State yet were admitted prior to Christmas. This is an outstanding way to approach “safeties.” Get the safety done early, and reduce anxiety.
I do not see any restrictions by Tulane on the location of the regular decision colleges.
By the way, it might (or might not) show serious interest in Tulane to apply to Loyola. At least it would show interest in New Orleans. I do not know, but maybe even mention Loyola to the admissions folks at Tulane. Also @fallenchemist is an expert on Tulane admissions. I hope that he chimes in here.
