Probably because the house without bids is in an undesirable location despite being "across the street".
Would you rather have a beachfront house, or a house across the street that has its view totally blocked by the beachfront house?
The people entering probably aren't trying to get their first house - they're trying to relocate the one they already have. And my next sentence that you so conveniently chopped out of the quote pointed out that people would still complain about not being able to get a specific location.
