Poorva was looped at Kulwa when Mahabodhi crossed Sasni. It was strange that a 130 mps train was looped even when other train was about 33 kms behind with Aligarh as stoppage also.
Both of the train are non stop from Aljn, so Poorva could have been given preference as Mb was much late compared to poorva.
Still nothing can be said about NCR. Unpredictable NCR _/\_
