If in that situation, forget cutting the main sheet, cut the tramp and sort yourself out from there...... It just may save your life
Exactly.
Get some air, then worry about un-tangling !
You need to think this thru as to what order you do things and have it clear in your mind.
1, Which way is up (trust me it's not as silly as it sounds)
2, Air route (cut tramp?)
3, Now breathing, less speed required
4, Un-tanglement
5, Recovery
