According to Srila Visvanatha Cakravarti, Krishna visited Srutadeva and Bahulasva at the same time by manifesting Himself in duplicate forms, along with the sages. Thus King Bahulasva thought that Lord Krishna had come only to his house, leaving Srutadeva to return home disappointed, while Srutadeva believed that just the reverse was the case.
In Krishna, Srila Prabhupada remarks, "That [Lord Krishna] and His companions were present in both houses, although both the brahmana and the King thought He was present in his house only, is another opulence of the Supreme Personality of Godhead. This opulence is described in the revealed scriptures as vaibhava-prakasa. Similarly, when Lord Krishna married sixteen thousand wives, He also expanded Himself into sixteen thousand forms, each one of them as powerful as He Himself. Similarly, in Vrindavana, when Brahma stole away Krishna's cows, calves and cowherd boys, Krishna expanded Himself into many new cows, calves and cowherd boys."
