This improves chances of getting onto a foreign channel and thus makes P2P a bit more reliable. Without scan burst it was possible for firmware to not switch to foreign channel resulting in "failed to switch to channel for roc scan" warning. This would also effectively fail some offchan tx requests and lead to P2P find/connect taking longer. This could be observed when other vifs were running/busy, e.g. with P2P GO.
