It could lead to that...esp in a long, indefinite hiatus. Their military enlistment, which looks like it's going to be done individually, starting with Jin will be finished by around 2028 to 2029, after JK completes his turn. So we are looking at 7 years before they come together again, as a group...if ever...And by this time they will have been out of contract with Hybe already.
We can, therefore, assume that BTS, as a band is actually no more... They just say "hiatus" to soften the blow to the clingy, vulnerable Army...
