Usually no. Normalize one preferred pair owner, then redirect or otherwise consolidate aliases so the same decision does not produce two competing pages.
Use case — Comparison pages
Comparison evidence, not verdicts
A vs B pages look like arithmetic — generate every pair and you have a content roadmap. The real question is which pairs represent a buyer decision your evidence can actually support.
Page-family model
The decision path
Real buyer decision
Start with a real user decision and a maintained source relationship.
Pair qualification
Keep pair qualification attached to the page-family decision before scale.
One pair owner
Keep one pair owner attached to the page-family decision before scale.
Comparable evidence
Keep comparable evidence attached to the page-family decision before scale.
Freshness
Keep freshness attached to the page-family decision before scale.
Quality Gate
Keep quality gate attached to the page-family decision before scale.
Source evidence model
Qualify the decision before generating the pair
One normalized pair should own the preferred URL, aliases, comparison dimensions, evidence states, and freshness record.

Evidence threshold
Unknown is not No
Comparison evidence needs more than a boolean. Explicit states keep missing, conditional, and inapplicable facts from becoming misleading verdicts.
Verified yes
Supported by current evidence
The source and review date are attached to the claim.
Conditional
True in a defined case
Plan, region, configuration, or workflow changes the answer.
Not verified
Evidence is missing
The page says what is unknown instead of converting absence into No.
Defensible inventory
Pair explosion is not a content strategy
One hundred products create 4,950 unique unordered pairs. Five hundred create 124,750. Qualification should reduce that arithmetic to real decisions.

Questions
Decisions before scale
The products need a shared buying context, decision-relevant dimensions, and enough current evidence to explain trade-offs without inventing a winner.
No. Missing evidence and negative evidence are different states. Collapsing them produces claims the source does not support.
No. Fact ownership and sourcing stay with the team. The page model keeps evidence state and freshness visible so unsupported claims can be reviewed.
Yes, when each page owns a distinct buyer task. Direct pairs, alternatives, and shortlists should not repeat the same evidence under different titles.
