Sure, but as the video shows, it currently looks rather janky when it happens, with the silhouette remaining even though the character is out and with full control. If the silhouette disappeared immediately there wouldn't be much of any issue.
Using Apollo's ult has an indicator with how far he will travel upon casting the ult, however, how far he actually travels is slightly further than the ult itself, which get's even more noticeable with ability range upgrades.
