Responding to my own question but it seems like I was messing around with this keyword in an inappropriate way. Correct code for sequential async file uploader goes like this:

JavaScript
function XMLHttpUploader(place, targetPHP)
{
	upload = function (currentArray, arrayTotalSize) {
	    var currentFile = currentArray.shift();
	    
	    if (currentFile) {
	        var xhr = new XMLHttpRequest();
	        xhr.open('POST', targetPHP, true);
	        xhr.setRequestHeader('UP-FILENAME', currentFile.name);
	        xhr.setRequestHeader('UP-SIZE', currentFile.size);
	        xhr.setRequestHeader('UP-TYPE', currentFile.type);
	        xhr.onreadystatechange = function () {
	            if (this.readyState == 4 && this.status == 200) {
	                var progressBar = document.querySelector('progress');
	                if (progressBar) {
	                    progressBar.value = Math.round(((arrayTotalSize - currentArray.length) * 100) / arrayTotalSize);
	                }

	                upload(currentArray, arrayTotalSize);
	            }
	        }
	        xhr.onerror = function () {
	            alert('File transfer failed!');
	        }
	        xhr.send(currentFile);
	    }
	    else {
	        var progressBar = document.querySelector('progress');
	        if (progressBar) {
	            progressBar.value = 100;
	            setTimeout("location.reload(true);", 2000);
	        }
	    }
	}

	// Function drop file
	this.drop = function(event) 
	{
	    event.preventDefault();
		var currentArray = new Array();
		for (var i = 0; i < event.dataTransfer.files.length; i++) {
		    currentArray.push(event.dataTransfer.files[i]);
		}
		upload(currentArray, currentArray.length);
	}
	
	// The inclusion of the event listeners (DragOver and drop)
	this.uploadPlace =  document.getElementById(place);
	this.uploadPlace.addEventListener("dragover", function(event)
	{
		event.stopPropagation(); 
		event.preventDefault();
	}, true);
	this.uploadPlace.addEventListener("drop", this.drop, false); 

}
