Pretty coincidental. Corriepedia says "This episode was transmitted at 6.50pm to allow for coverage of Euro 96 football" so I wonder if it was an accelerated flow style junction to get into the football ASAP. You'd think a master copy would have the usual credits though, even if Granada had been asked at the last minute to edit them out.
It was a very tight schedule that afternoon / evening, with both Semi Finals taking place, one kicking off at 4pm and the other at 7:30pm. Both the BBC and ITV were showing both Semi Finals, the agreement being that if England or Scotland were in one, both channels could show it. That meant both had the option of showing the other Semi Final as well.
The first Semi-Final (France v Czech Republic) kicked off at 4pm, but went to extra time and penalties so is unlikely to have been off the air much before 6:40pm. I seem to remember the BBC dropping Neighbours and having short national and local news bulletins to get back on the air for build up to the England Semi Final at 7:10pm.
I'm not sure what ITV did that evening, but if they were trying to get any sort of national (and local) bulletins in as well as Corrie before 7:20pm, it would have been very tight for time.
